How do I remove emoji code using JavaScript? I thought I had taken care of it using the code below, but I still have characters like 🔴.
function removeInvalidChars() {
return this.replace(/[\uE000-\uF8FF]/g, '');
}
For me none of the answers completely removed all emojis so I had to do some work myself and this is what i got :
text.replace(/([\u2700-\u27BF]|[\uE000-\uF8FF]|\uD83C[\uDC00-\uDFFF]|\uD83D[\uDC00-\uDFFF]|[\u2011-\u26FF]|\uD83E[\uDD10-\uDDFF])/g, '');
Also, it should take into account that if one inserting the string later to the database, replacing with empty string could expose security issue. instead replace with the replacement character U+FFFD, see : http://www.unicode.org/reports/tr36/#Deletion_of_Noncharacters
The range you have selected is the Private Use Area, containing non-standard characters. Carriers used to encode emoji as different, inconsistent values inside this range.
More recently, the emoji have been given standardised 'unified' codepoints. Many of these are outside of the Basic Multilingual Plane, in the block U+1F300–U+1F5FF, including your example 🔴 U+1F534 Large Red Circle.
You could detect these characters with [\U0001F300-\U0001F5FF] in a regex engine that supported non-BMP characters, but JavaScript's RegExp is not such a beast. Unfortunately the JS string model is based on UTF-16 code units, so you'd have to work with the UTF-16 surrogates in a regexp:
return this.replace(/([\uE000-\uF8FF]|\uD83C[\uDF00-\uDFFF]|\uD83D[\uDC00-\uDDFF])/g, '')
However, note that there are other characters in the Basic Multilingual Plane that are used as emoji by phones but which long predate emoji. For example U+2665 is the traditional Heart Suit character ♥, but it may be rendered as an emoji graphic on some devices. It's up to you whether you treat this as emoji and try to remove it. See this list for more examples.
I solved it by using a regex with Unicode property escapes. I got it from this article, it's for Java but still very helpful - Remove Emojis from a Java String.
'Smile😀'.replace(/[^\p{L}\p{N}\p{P}\p{Z}^$\n]/gu, '');
It removes all symbols except:
\p{L} - all letters from any language
\p{N} - numbers
\p{P} - punctuation
\p{Z} - whitespace separators
^$\n - add any symbols you want to keep
This one should be more correct and it works, but for me it leaves some trash symbols in the string:
'Smile😀'.replace(/\p{Emoji}/gu, '');
Edit: added symbols from comments
I've found many suggestions around but the regex that have solved my problem is:
/(?:[\u2700-\u27bf]|(?:\ud83c[\udde6-\uddff]){2}|[\ud800-\udbff][\udc00-\udfff]|[\u0023-\u0039]\ufe0f?\u20e3|\u3299|\u3297|\u303d|\u3030|\u24c2|\ud83c[\udd70-\udd71]|\ud83c[\udd7e-\udd7f]|\ud83c\udd8e|\ud83c[\udd91-\udd9a]|\ud83c[\udde6-\uddff]|\ud83c[\ude01-\ude02]|\ud83c\ude1a|\ud83c\ude2f|\ud83c[\ude32-\ude3a]|\ud83c[\ude50-\ude51]|\u203c|\u2049|[\u25aa-\u25ab]|\u25b6|\u25c0|[\u25fb-\u25fe]|\u00a9|\u00ae|\u2122|\u2139|\ud83c\udc04|[\u2600-\u26FF]|\u2b05|\u2b06|\u2b07|\u2b1b|\u2b1c|\u2b50|\u2b55|\u231a|\u231b|\u2328|\u23cf|[\u23e9-\u23f3]|[\u23f8-\u23fa]|\ud83c\udccf|\u2934|\u2935|[\u2190-\u21ff])/g
A short example
function removeEmojis (string) {
var regex = /(?:[\u2700-\u27bf]|(?:\ud83c[\udde6-\uddff]){2}|[\ud800-\udbff][\udc00-\udfff]|[\u0023-\u0039]\ufe0f?\u20e3|\u3299|\u3297|\u303d|\u3030|\u24c2|\ud83c[\udd70-\udd71]|\ud83c[\udd7e-\udd7f]|\ud83c\udd8e|\ud83c[\udd91-\udd9a]|\ud83c[\udde6-\uddff]|\ud83c[\ude01-\ude02]|\ud83c\ude1a|\ud83c\ude2f|\ud83c[\ude32-\ude3a]|\ud83c[\ude50-\ude51]|\u203c|\u2049|[\u25aa-\u25ab]|\u25b6|\u25c0|[\u25fb-\u25fe]|\u00a9|\u00ae|\u2122|\u2139|\ud83c\udc04|[\u2600-\u26FF]|\u2b05|\u2b06|\u2b07|\u2b1b|\u2b1c|\u2b50|\u2b55|\u231a|\u231b|\u2328|\u23cf|[\u23e9-\u23f3]|[\u23f8-\u23fa]|\ud83c\udccf|\u2934|\u2935|[\u2190-\u21ff])/g;
return string.replace(regex, '');
}
Hope it can help you
Just an addition to #hababr answer.
If you need to get rid of complicated emojis, you have to remove also additional things like modifiers and etc:
'👨🏿🎤'.replace(/[\p{Emoji}\p{Emoji_Modifier}\p{Emoji_Component}\p{Emoji_Modifier_Base}\p{Emoji_Presentation}]/gu, '').charCodeAt(0)
update:
*#0-9 - are Emoji characters with a text representation by default, per the Unicode Standard.
so, my current solution is next:
'👨🏿🎤'.replace(/(?![*#0-9]+)[\p{Emoji}\p{Emoji_Modifier}\p{Emoji_Component}\p{Emoji_Modifier_Base}\p{Emoji_Presentation}]/gu, '').charCodeAt(0)
I know this post is a bit old, but I stumbled across this very problem at work and a colleague came up with an interesting idea. Basically instead of stripping emoji character only allow valid characters in. Consulting this ASCII table:
http://www.asciitable.com/
A function such as this could only keep legal characters (the range itself dependent on what you are after)
function (input) {
var result = '';
if (input.length == 0)
return input;
for (var indexOfInput = 0, lengthOfInput = input.length; indexOfInput < lengthOfInput; indexOfInput++) {
var charAtSpecificIndex = input[indexOfInput].charCodeAt(0);
if ((32 <= charAtSpecificIndex) && (charAtSpecificIndex <= 126)) {
result += input[indexOfInput];
}
}
return result;
};
This should preserve all numbers, letters and special characters of the Alphabet for a situation where you wish to preserve the English alphabet + number + special characters. Hope it helps someone :)
#bobince's solution didn't work for me. Either the Emojis stayed there or they were swapped by a different Emoji.
This solution did the trick for me:
var ranges = [
'\ud83c[\udf00-\udfff]', // U+1F300 to U+1F3FF
'\ud83d[\udc00-\ude4f]', // U+1F400 to U+1F64F
'\ud83d[\ude80-\udeff]' // U+1F680 to U+1F6FF
];
$('#mybtn').on('click', function() {
removeInvalidChars();
})
function removeInvalidChars() {
var str = $('#myinput').val();
str = str.replace(new RegExp(ranges.join('|'), 'g'), '');
$("#myinput").val(str);
}
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<input type="text" id="myinput"/>
<input type="submit" id="mybtn" value="clear"/>

After searching and trying lots of unicode regex, I suggest you try this, it can cover all of emojis:
function removeEmoji(str) {
let strCopy = str;
const emojiKeycapRegex = /[\u0023-\u0039]\ufe0f?\u20e3/g;
const emojiRegex = /\p{Extended_Pictographic}/gu;
const emojiComponentRegex = /\p{Emoji_Component}/gu;
if (emojiKeycapRegex.test(strCopy)) {
strCopy = strCopy.replace(emojiKeycapRegex, '');
}
if (emojiRegex.test(strCopy)) {
strCopy = strCopy.replace(emojiRegex, '');
}
if (emojiComponentRegex.test(strCopy)) {
// eslint-disable-next-line no-restricted-syntax
for (const emoji of (strCopy.match(emojiComponentRegex) || [])) {
if (/[\d|*|#]/.test(emoji)) {
continue;
}
strCopy = strCopy.replace(emoji, '');
}
}
return strCopy;
}
let a = "1️⃣aa🤹♂️b#️⃣🔤✅❎23#!^*bb🤹🏾🤹♀️🚴🏻ccc";
console.log(removeEmoji(a))
Refrence: Unicode Emoij Document
None of the answers here worked for all the unicode characters I tested (specifically characters in the miscellaneous range such as ⛽ or ☯️).
Here is one that worked for me, (heavily) inspired from this SO PHP answer:
function _removeEmojis(str) {
return str.replace(/([#0-9]\u20E3)|[\xA9\xAE\u203C\u2047-\u2049\u2122\u2139\u3030\u303D\u3297\u3299][\uFE00-\uFEFF]?|[\u2190-\u21FF][\uFE00-\uFEFF]?|[\u2300-\u23FF][\uFE00-\uFEFF]?|[\u2460-\u24FF][\uFE00-\uFEFF]?|[\u25A0-\u25FF][\uFE00-\uFEFF]?|[\u2600-\u27BF][\uFE00-\uFEFF]?|[\u2900-\u297F][\uFE00-\uFEFF]?|[\u2B00-\u2BF0][\uFE00-\uFEFF]?|(?:\uD83C[\uDC00-\uDFFF]|\uD83D[\uDC00-\uDEFF])[\uFE00-\uFEFF]?/g, '');
}
(My use case is sorting in a data grid where emojis can come first in a string but users want the text ordered by the actual words.)
sandre89's answer is good but not perfect.
I spent some time on the subject and have a working solution.
var ranges = [
'[\u00A0-\u269f]',
'[\u26A0-\u329f]',
// The following characters could not be minified correctly
// if specifed with the ES6 syntax \u{1F400}
'[🀄-🧀]'
//'[\u{1F004}-\u{1F9C0}]'
];
$('#mybtn').on('click', function() {
removeInvalidChars();
});
function removeInvalidChars() {
var str = $('#myinput').val();
str = str.replace(new RegExp(ranges.join('|'), 'ug'), '');
$("#myinput").val(str);
}
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<input type="text" id="myinput" />
<input type="submit" id="mybtn" value="clear" />
Here is my CodePen
There are some points to note, though.
Unicode characters from U+1F000 up need a special notation, so you can use sandre89's way, or opt for the \u{1F000} ES6 notation, which may or may not work with your minificator. I succeeded pasting the emojis directly in the UTF-8 encoded script.
Don't forget the u flag in the regex, or your Javascript engine may throw an error.
Beware that things may not be working due to the file encoding, character set, or minificator. In my case nothing worked until I took the script off an .isml file (Demandware) and pasted it into a .js file.
You may gain some insight by referring to Wikipedia Emoji page and How many bytes does one Unicode character take?, and by tinkering with this Online Unicode converter, as I did.
var emoji =/([#0-9]\u20E3)|[\xA9\xAE\u203C\u2047-\u2049\u2122\u2139\u3030\u303D\u3297\u3299][\uFE00-\uFEFF]?|[\u2190-\u21FF][\uFE00-\uFEFF]?|[\u2300-\u23FF][\uFE00-\uFEFF]?|[\u2460-\u24FF][\uFE00-\uFEFF]?|[\u25A0-\u25FF][\uFE00-\uFEFF]?|[\u2600-\u27BF][\uFE00-\uFEFF]?|[\u2900-\u297F][\uFE00-\uFEFF]?|[\u2B00-\u2BF0][\uFE00-\uFEFF]?|(?:\uD83C[\uDC00-\uDFFF]|\uD83D[\uDC00-\uDEFF])[\uFE00-\uFEFF]?|[\u20E3]|[\u26A0-\u3000]|\uD83E[\udd00-\uddff]|[\u00A0-\u269F]/g;
str.replace(emoji, "");
i add this '\uD83E[\udd00-\uddff]'
these emojis were updated when 2018 june
if u want block emojis after other update then use this
str.replace(/[^0-9a-zA-Zㄱ-힣+×÷=%♤♡☆♧)(*&^/~##!-:;,?`_|<>{}¥£€$◇■□●○•°※¤《》¡¿₩\[\]\"\' \\]/g ,"");
u can block all emojis and u can only use eng, num, hangle, and some Characters
thx :)
You can use this function to replace emojis with nothing:
function msgAfterClearEmojis(msg)
{
var new_msg = msg.replace(/([#0-9]\u20E3)|[\xA9\xAE\u203C\u2047-\u2049\u2122\u2139\u3030\u303D\u3297\u3299][\uFE00-\uFEFF]?|[\u2190-\u21FF][\uFE00-\uFEFF]?|[\u2300-\u23FF][\uFE00-\uFEFF]?|[\u2460-\u24FF][\uFE00-\uFEFF]?|[\u25A0-\u25FF][\uFE00-\uFEFF]?|[\u2600-\u27BF][\uFE00-\uFEFF]?|[\u2900-\u297F][\uFE00-\uFEFF]?|[\u2B00-\u2BF0][\uFE00-\uFEFF]?|(?:\uD83C[\uDC00-\uDFFF]|\uD83D[\uDC00-\uDEFF])[\uFE00-\uFEFF]?|[\u20E3]|[\u26A0-\u3000]|\uD83E[\udd00-\uddff]|[\u00A0-\u269F]/g, '').trim();
return new_msg;
}

This is the iteration on #hababr's answer.
His answer removes lots of standard chars like $, +, < and so on.
This version keeps all of them (except for the \ backslash - dunno how to properly escape it).
"hey😁 hau💓 ahoy🏴☠️ !##$%^&*()-_=+±§;:'\|`~/?[]{},.<>".replace(/[^\p{L}\p{N}\p{P}\p{Z}{^$=+±\\'|`\\~<>}]/gu, "")
// "hey hau ahoy !##$%^&*()-_=+±§;:'|`~/?[]{},.<>"
I have this regex and it works for all emojis i found on this page
try this regex

There is a modern solution using categories
Modern browsers support Unicode property, which allows you to match emojis based on their belonging in the Emoji Unicode category. For example, you can use Unicode property escapes like \p{Emoji} or \P{Emoji} to match/no match emoji characters. Note that 0123456789#* and other characters are interpreted as emojis using the previous Unicode category. Therefore, a better way to do this is to use the {Extended_Pictographic} Unicode category that denotes all the characters typically understood as emojis instead of the {Emoji} category.
const withEmojis = /\p{Extended_Pictographic}/u
withEmojis.test('😀😀');
//true
withEmojis.test('ab');
//false
withEmojis.test('1');
//false
or with negation
const noEmojis = /\P{Extended_Pictographic}/u
noEmojis.test('😀');
//false
noEmojis.test('1212');
//false
You can use mathiasbynens/emoji-regex package to remove or replace emojis.
You can see the latest build's content to grab the regex by visiting following url:
http://unpkg.com/emoji-regex/index.js
function removeEmoji (content) {
let conByte = new TextEncoder("utf-8").encode(content);
for (let i = 0; i < conByte.length; i++) {
if ((conByte[i] & 0xF8) == 0xF0) {
for (let j = 0; j < 4; j++) {
conByte[i+j]=0x30;
}
i += 3;
}
}
content = new TextDecoder("utf-8").decode(conByte);
return content.replaceAll("0000", "");
}
How do I remove emoji code using JavaScript? I thought I had taken care of it using the code below, but I still have characters like 🔴.
function removeInvalidChars() {
return this.replace(/[\uE000-\uF8FF]/g, '');
}
For me none of the answers completely removed all emojis so I had to do some work myself and this is what i got :
text.replace(/([\u2700-\u27BF]|[\uE000-\uF8FF]|\uD83C[\uDC00-\uDFFF]|\uD83D[\uDC00-\uDFFF]|[\u2011-\u26FF]|\uD83E[\uDD10-\uDDFF])/g, '');
Also, it should take into account that if one inserting the string later to the database, replacing with empty string could expose security issue. instead replace with the replacement character U+FFFD, see : http://www.unicode.org/reports/tr36/#Deletion_of_Noncharacters
The range you have selected is the Private Use Area, containing non-standard characters. Carriers used to encode emoji as different, inconsistent values inside this range.
More recently, the emoji have been given standardised 'unified' codepoints. Many of these are outside of the Basic Multilingual Plane, in the block U+1F300–U+1F5FF, including your example 🔴 U+1F534 Large Red Circle.
You could detect these characters with [\U0001F300-\U0001F5FF] in a regex engine that supported non-BMP characters, but JavaScript's RegExp is not such a beast. Unfortunately the JS string model is based on UTF-16 code units, so you'd have to work with the UTF-16 surrogates in a regexp:
return this.replace(/([\uE000-\uF8FF]|\uD83C[\uDF00-\uDFFF]|\uD83D[\uDC00-\uDDFF])/g, '')
However, note that there are other characters in the Basic Multilingual Plane that are used as emoji by phones but which long predate emoji. For example U+2665 is the traditional Heart Suit character ♥, but it may be rendered as an emoji graphic on some devices. It's up to you whether you treat this as emoji and try to remove it. See this list for more examples.
I solved it by using a regex with Unicode property escapes. I got it from this article, it's for Java but still very helpful - Remove Emojis from a Java String.
'Smile😀'.replace(/[^\p{L}\p{N}\p{P}\p{Z}^$\n]/gu, '');
It removes all symbols except:
\p{L} - all letters from any language
\p{N} - numbers
\p{P} - punctuation
\p{Z} - whitespace separators
^$\n - add any symbols you want to keep
This one should be more correct and it works, but for me it leaves some trash symbols in the string:
'Smile😀'.replace(/\p{Emoji}/gu, '');
Edit: added symbols from comments
I've found many suggestions around but the regex that have solved my problem is:
/(?:[\u2700-\u27bf]|(?:\ud83c[\udde6-\uddff]){2}|[\ud800-\udbff][\udc00-\udfff]|[\u0023-\u0039]\ufe0f?\u20e3|\u3299|\u3297|\u303d|\u3030|\u24c2|\ud83c[\udd70-\udd71]|\ud83c[\udd7e-\udd7f]|\ud83c\udd8e|\ud83c[\udd91-\udd9a]|\ud83c[\udde6-\uddff]|\ud83c[\ude01-\ude02]|\ud83c\ude1a|\ud83c\ude2f|\ud83c[\ude32-\ude3a]|\ud83c[\ude50-\ude51]|\u203c|\u2049|[\u25aa-\u25ab]|\u25b6|\u25c0|[\u25fb-\u25fe]|\u00a9|\u00ae|\u2122|\u2139|\ud83c\udc04|[\u2600-\u26FF]|\u2b05|\u2b06|\u2b07|\u2b1b|\u2b1c|\u2b50|\u2b55|\u231a|\u231b|\u2328|\u23cf|[\u23e9-\u23f3]|[\u23f8-\u23fa]|\ud83c\udccf|\u2934|\u2935|[\u2190-\u21ff])/g

Hope it can help you
Just an addition to #hababr answer.
If you need to get rid of complicated emojis, you have to remove also additional things like modifiers and etc:
'👨🏿🎤'.replace(/[\p{Emoji}\p{Emoji_Modifier}\p{Emoji_Component}\p{Emoji_Modifier_Base}\p{Emoji_Presentation}]/gu, '').charCodeAt(0)
update:
*#0-9 - are Emoji characters with a text representation by default, per the Unicode Standard.
so, my current solution is next:
'👨🏿🎤'.replace(/(?![*#0-9]+)[\p{Emoji}\p{Emoji_Modifier}\p{Emoji_Component}\p{Emoji_Modifier_Base}\p{Emoji_Presentation}]/gu, '').charCodeAt(0)
I know this post is a bit old, but I stumbled across this very problem at work and a colleague came up with an interesting idea. Basically instead of stripping emoji character only allow valid characters in. Consulting this ASCII table:
http://www.asciitable.com/
A function such as this could only keep legal characters (the range itself dependent on what you are after)
function (input) {
var result = '';
if (input.length == 0)
return input;
for (var indexOfInput = 0, lengthOfInput = input.length; indexOfInput < lengthOfInput; indexOfInput++) {
var charAtSpecificIndex = input[indexOfInput].charCodeAt(0);
if ((32 <= charAtSpecificIndex) && (charAtSpecificIndex <= 126)) {
result += input[indexOfInput];
}
}
return result;
};
This should preserve all numbers, letters and special characters of the Alphabet for a situation where you wish to preserve the English alphabet + number + special characters. Hope it helps someone :)
#bobince's solution didn't work for me. Either the Emojis stayed there or they were swapped by a different Emoji.
This solution did the trick for me:
var ranges = [
'\ud83c[\udf00-\udfff]', // U+1F300 to U+1F3FF
'\ud83d[\udc00-\ude4f]', // U+1F400 to U+1F64F
'\ud83d[\ude80-\udeff]' // U+1F680 to U+1F6FF
];
$('#mybtn').on('click', function() {
removeInvalidChars();
})
function removeInvalidChars() {
var str = $('#myinput').val();
str = str.replace(new RegExp(ranges.join('|'), 'g'), '');
$("#myinput").val(str);
}
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<input type="text" id="myinput"/>
<input type="submit" id="mybtn" value="clear"/>

After searching and trying lots of unicode regex, I suggest you try this, it can cover all of emojis:
function removeEmoji(str) {
let strCopy = str;
const emojiKeycapRegex = /[\u0023-\u0039]\ufe0f?\u20e3/g;
const emojiRegex = /\p{Extended_Pictographic}/gu;
const emojiComponentRegex = /\p{Emoji_Component}/gu;
if (emojiKeycapRegex.test(strCopy)) {
strCopy = strCopy.replace(emojiKeycapRegex, '');
}
if (emojiRegex.test(strCopy)) {
strCopy = strCopy.replace(emojiRegex, '');
}
if (emojiComponentRegex.test(strCopy)) {
// eslint-disable-next-line no-restricted-syntax
for (const emoji of (strCopy.match(emojiComponentRegex) || [])) {
if (/[\d|*|#]/.test(emoji)) {
continue;
}
strCopy = strCopy.replace(emoji, '');
}
}
return strCopy;
}
let a = "1️⃣aa🤹♂️b#️⃣🔤✅❎23#!^*bb🤹🏾🤹♀️🚴🏻ccc";
console.log(removeEmoji(a))

None of the answers here worked for all the unicode characters I tested (specifically characters in the miscellaneous range such as ⛽ or ☯️).
Here is one that worked for me, (heavily) inspired from this SO PHP answer:
function _removeEmojis(str) {
return str.replace(/([#0-9]\u20E3)|[\xA9\xAE\u203C\u2047-\u2049\u2122\u2139\u3030\u303D\u3297\u3299][\uFE00-\uFEFF]?|[\u2190-\u21FF][\uFE00-\uFEFF]?|[\u2300-\u23FF][\uFE00-\uFEFF]?|[\u2460-\u24FF][\uFE00-\uFEFF]?|[\u25A0-\u25FF][\uFE00-\uFEFF]?|[\u2600-\u27BF][\uFE00-\uFEFF]?|[\u2900-\u297F][\uFE00-\uFEFF]?|[\u2B00-\u2BF0][\uFE00-\uFEFF]?|(?:\uD83C[\uDC00-\uDFFF]|\uD83D[\uDC00-\uDEFF])[\uFE00-\uFEFF]?/g, '');
}
(My use case is sorting in a data grid where emojis can come first in a string but users want the text ordered by the actual words.)
sandre89's answer is good but not perfect.
I spent some time on the subject and have a working solution.
var ranges = [
'[\u00A0-\u269f]',
'[\u26A0-\u329f]',
// The following characters could not be minified correctly
// if specifed with the ES6 syntax \u{1F400}
'[🀄-🧀]'
//'[\u{1F004}-\u{1F9C0}]'
];
$('#mybtn').on('click', function() {
removeInvalidChars();
});
function removeInvalidChars() {
var str = $('#myinput').val();
str = str.replace(new RegExp(ranges.join('|'), 'ug'), '');
$("#myinput").val(str);
}
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<input type="text" id="myinput" />
<input type="submit" id="mybtn" value="clear" />
Here is my CodePen
There are some points to note, though.
Unicode characters from U+1F000 up need a special notation, so you can use sandre89's way, or opt for the \u{1F000} ES6 notation, which may or may not work with your minificator. I succeeded pasting the emojis directly in the UTF-8 encoded script.
Don't forget the u flag in the regex, or your Javascript engine may throw an error.
Beware that things may not be working due to the file encoding, character set, or minificator. In my case nothing worked until I took the script off an .isml file (Demandware) and pasted it into a .js file.
You may gain some insight by referring to Wikipedia Emoji page and How many bytes does one Unicode character take?, and by tinkering with this Online Unicode converter, as I did.
var emoji =/([#0-9]\u20E3)|[\xA9\xAE\u203C\u2047-\u2049\u2122\u2139\u3030\u303D\u3297\u3299][\uFE00-\uFEFF]?|[\u2190-\u21FF][\uFE00-\uFEFF]?|[\u2300-\u23FF][\uFE00-\uFEFF]?|[\u2460-\u24FF][\uFE00-\uFEFF]?|[\u25A0-\u25FF][\uFE00-\uFEFF]?|[\u2600-\u27BF][\uFE00-\uFEFF]?|[\u2900-\u297F][\uFE00-\uFEFF]?|[\u2B00-\u2BF0][\uFE00-\uFEFF]?|(?:\uD83C[\uDC00-\uDFFF]|\uD83D[\uDC00-\uDEFF])[\uFE00-\uFEFF]?|[\u20E3]|[\u26A0-\u3000]|\uD83E[\udd00-\uddff]|[\u00A0-\u269F]/g;
str.replace(emoji, "");
i add this '\uD83E[\udd00-\uddff]'
these emojis were updated when 2018 june
if u want block emojis after other update then use this
str.replace(/[^0-9a-zA-Zㄱ-힣+×÷=%♤♡☆♧)(*&^/~##!-:;,?`_|<>{}¥£€$◇■□●○•°※¤《》¡¿₩\[\]\"\' \\]/g ,"");
u can block all emojis and u can only use eng, num, hangle, and some Characters
thx :)
You can use this function to replace emojis with nothing:
function msgAfterClearEmojis(msg)
{
var new_msg = msg.replace(/([#0-9]\u20E3)|[\xA9\xAE\u203C\u2047-\u2049\u2122\u2139\u3030\u303D\u3297\u3299][\uFE00-\uFEFF]?|[\u2190-\u21FF][\uFE00-\uFEFF]?|[\u2300-\u23FF][\uFE00-\uFEFF]?|[\u2460-\u24FF][\uFE00-\uFEFF]?|[\u25A0-\u25FF][\uFE00-\uFEFF]?|[\u2600-\u27BF][\uFE00-\uFEFF]?|[\u2900-\u297F][\uFE00-\uFEFF]?|[\u2B00-\u2BF0][\uFE00-\uFEFF]?|(?:\uD83C[\uDC00-\uDFFF]|\uD83D[\uDC00-\uDEFF])[\uFE00-\uFEFF]?|[\u20E3]|[\u26A0-\u3000]|\uD83E[\udd00-\uddff]|[\u00A0-\u269F]/g, '').trim();

This is the iteration on #hababr's answer.
His answer removes lots of standard chars like $, +, < and so on.
This version keeps all of them (except for the \ backslash - dunno how to properly escape it).
"hey😁 hau💓 ahoy🏴☠️ !##$%^&*()-_=+±§;:'\|`~/?[]{},.<>".replace(/[^\p{L}\p{N}\p{P}\p{Z}{^$=+±\\'|`\\~<>}]/gu, "")

There is a modern solution using categories
Modern browsers support Unicode property, which allows you to match emojis based on their belonging in the Emoji Unicode category. For example, you can use Unicode property escapes like \p{Emoji} or \P{Emoji} to match/no match emoji characters. Note that 0123456789#* and other characters are interpreted as emojis using the previous Unicode category. Therefore, a better way to do this is to use the {Extended_Pictographic} Unicode category that denotes all the characters typically understood as emojis instead of the {Emoji} category.
const withEmojis = /\p{Extended_Pictographic}/u
withEmojis.test('😀😀');
//true
withEmojis.test('ab');
//false
withEmojis.test('1');
//false
or with negation
const noEmojis = /\P{Extended_Pictographic}/u
noEmojis.test('😀');
//false
noEmojis.test('1212');
//false
You can use mathiasbynens/emoji-regex package to remove or replace emojis.
You can see the latest build's content to grab the regex by visiting following url:
http://unpkg.com/emoji-regex/index.js
In detail, this function first uses TextEncoder to convert content into a byte array with utf-8 encoding, then loops through this array, if it finds a byte whose first five bits are 11110 (i.e. 0xF0), it means this is an emoji start, then it replaces this byte and the next three bytes with 0x30 (i.e. number 0). Finally, it uses TextDecoder to convert the modified byte array back to a string, and uses replaceAll method to remove extra 0s.
function removeEmoji (content) {
let conByte = new TextEncoder("utf-8").encode(content);
for (let i = 0; i < conByte.length; i++) {
if ((conByte[i] & 0xF8) == 0xF0) {
for (let j = 0; j < 4; j++) {
conByte[i+j]=0x30;
}
i += 3;
}
}
content = new TextDecoder("utf-8").decode(conByte);
return content.replaceAll("0000", "");
}
Have a question. Sorry for my English.
I have a string. Customer enter SMS text at text-area.
How can I find the existing character of utf-16 at the string or not?
At php I check this code:
if (iconv("UTF-8","UTF-8//IGNORE",$_entry_text) != $_entry_text) {
// exist utf-16
}
How can I at Javascript check? Try to find an answer the second day ((
Thanks.
A string is a series of characters, each which have a character code. ASCII defines characters from 0 to 127, so if a character in the string has a code greater than that, then it is a Unicode character. This function checks for that. See String#charCodeAt.
function hasUnicode (str) {
for (var i = 0; i < str.length; i++) {
if (str.charCodeAt(i) > 127)
return true;
}
return false;
}
Then use it like, hasUnicode("Test message");
If it's a short string, one method would be to just look across the length of it and check if any of the char-codes sit outside of the single-byte 0-255 range
if (_entry_text.charCodeAt(i) > 255) ...
I think there is no need for a loop;
var ascii = /^[ -~]+$/;
ascii.test("Sefa"); // it is true no non-ascii characters
ascii.test("Sefa£"); // it is false there is non-ascii character
I tried using toUppercase() method to convert japanese characters to uppercase but it return same string with out conversion.
Is there any other way to do this using jquery or javascript.
fieldValue = "ショウコ"; //japanese string.
function convertToUppercase(fieldValue)
{
convertedValue = fieldValue.toUpperCase();
return convertedValue;
}
Any help would be greatly appreciated!
There's a list of all the "small" letters (known as "youon") on Wikipedia:
ぁぃぅぇぉっゃゅょゎァィゥェォヵㇰヶㇱㇲッㇳㇴㇵㇶㇷㇷ゚ㇸㇹㇺャュョㇻㇼㇽㇾㇿヮ
You could use a switch statement to convert them to their "big" equivalents, which I'll type out here for your convenience:
あいうえおつやゆよわアイウエオカクケシスツトヌハヒフプヘホムヤユヨラリルレロワ
Note that the consonants aren't necessarily read the same way when they're made "big"; for example, 何ヶ月 is read "なんかげつ(nankagetsu)", not "なんけげつ(nankegetsu)". っ, which indicates a glottal stop on the next syllable, is read as "tsu" when it's made big.
The "big" vowels indicate that they need to be given their own syllable length. (There's a term for this too, but I'm not a linguist -- sorry!)
I'm a bit ignorant on the names of Japanese characters but I do know that Sugar.js has many methods for manipulating and transforming such characters. It has methods such as zenkaku, hankaku, hiragana, and katakana.
Here's a link to the Sugarjs' String API
Thanks for the help and guided me to right way
Finally I came up with this solution.
function convertBigKana(kanaVal){
var smallKana = Array('ァ','ィ','ゥ','ェ','ォ','ヵ','ヶ','ㇱ','ㇲ','ッ','ㇳ','ㇴ','ㇵ','ㇶ','ㇷ','ㇸ','ㇹ','ㇺ','ャ','ュ','ョ','ㇻ','ㇼ','ㇽ','ㇾ','ㇿ','ヮ');
var bigKana = Array('ア','イ','ウ','エ','オ','カ','ケ','シ','ス','ツ','ト','ヌ','ハ','ヒ','フ','ヘ','ホ','ム','ヤ','ユ','ヨ','ラ','リ','ル','レ','ロ','ワ');
var ckanaVal = '';
for (var i = 0; i < kanaVal.length; i++){
//var index = smallKana.indexOf(kanaVal.charAt(i)); //indexOf and stri[i] don't work on ie
var index = jQuery.inArray(kanaVal.charAt(i), smallKana);
if (index !== -1) {
ckanaVal+= bigKana[index];
}
else
{
ckanaVal+= kanaVal.charAt(i);
}
}
return ckanaVal;
}
i am trying to split a TextArea value where a pattern does not match
the text is like following:
Some Good Tutorials
http://a.com/page1
http://a.com/page2
Some Good Images
http://i.com/p1
http://i.com/p2
Some Good Videos
http://m.com/p1
http://m.com/p2
now i want to get only the links from the text so a better solution would be to split the whole string in an array of strings where the a line is not a url and then from amongst this array split each string with "\n"
edit:
okay i found a solution, i can find lines which does not begin with http:// or https:// and replace them with a good place holder after than i can get the links
though i am weak in regex so can someone tell me how to do this in javascript?
Match the pattern. don't split with it.
value=value.match(/http\:\/\/.+/g)
(.+matches everything to the end of a line)
Solved finally! Here is the code:
function split_lines() {
var oText = $('linkTxtArea').value;
removeBlankLines(); // a helper function to remove blank lines
oText = oText.split("\n"); // first split the string into an array
for (i = 0; i < oText.length; i++) // loop over the array
{
if (!oText[i].match(/^http:/)) // check to see if the line does not begins with http:
{
oText[i] = oText[i].replace(oText[i], "!replaced!"); // replace it with '!replaced!'
}
}
oText = oText.toString().split("!replaced!"); // now join the array to a string and then split that string by '!replaced!'
for (i = 1; i < oText.length; i++)
{
oText[i] = oText[i].replace(/^,/,"").replace(/,$/,""); // there were some extra commas left so i fixed it
}
return oText;
}
