I'm trying to display the pound symbol in HTML (from PHP) but all I get is a symbol with a question mark.
The following are things that I've tried.
In PHP:
header('Content-type: text/html; charset=utf-8');
In HTML, put this in the head tag:
<meta http-equiv="Content-Type" content="text/html; charset=utf-8" />
I tried displaying it using a javascript function which converts it to:
�
I suppose it would help if I knew what I was doing... but I guess that's why I'm asking this question :)
Educated guess: You have a ISO-8859-1 encoded pound sign in a UTF-8 encoded page.
Make sure your data is in the right encoding and everything will work fine.
Use £. I had the same problem and solved it using jQuery:
$(this).text('£');
If you try this and it does not work, just change the jQuery methods,
$(this).html('£');
This always work in all contexts...
1st: the pound symbol is a "special" char in utf8 encoding (try saving £$ in a iso-8859-1 (or iso-8859-15) file and you will get ä when encoding using header)
2nd: change your encoding to utf8 form the file.
there are plenty of methods to do it.
notepad and notepad++ are great sugestions.
3rd: use ob_start(); (in php) BEFORE YOU MAKE ANY OUTPUT if you are getting weird encoding errors, like missing the encoding sometimes.
and YES, this solves it!
this kind of errors occurs when a page is encoded in windows-1252(ANSI),ASCII,iso-8859-1(5) and then you have all the others in utf8.
this is a terrible error and can cause weird things like session_start(); not working.
4th: other php solutions:
utf8_encode('£');
htmlentities('£');
echo '£';
5th: javascript solutions:
document.getElementById('id_goes_here').innerText.replace('£','£');
document.getElementById('id_goes_here').innerText.replace('£',"\u00A3");
$(this).html().replace('£','£'); //jquery
$(this).html().replace('£',"\u00A3"); //jquery
String.fromCharCode('163');
you MUST send £, so it will repair the broken encoded code point.
please, avoid these solutions!
use php!
these solutions only show how to 'fix' the error, and the last one only to create the well-encoded char.
Have you tried displaying a £ ?
Here is an overwhelming list.
You could try using £ or £ instead of embedding the character directly; if you embed it directly, you're more likely to run into encoding issues in which your editor saves the file is ISO-8859-1 but it's interpreted as UTF-8, or vice versa.
If you want to embed it (or other Unicode characters) directly, make sure you actually save your file as UTF-8, and set the encoding as you did with the Content-Type header. Make sure when you get the file from the server that the header is present and correct, and that the file hasn't been transcoded by the web server.
Or for other code equivalents try:
£
£
You need to save your PHP script file in UTF-8 encoding, and leave the <meta http-equiv="Content-Type" content="text/html; charset=utf-8" /> in the HTML.
For text editor, I recommend Notepad++, because it can detect and display the actual encoding of the file (in the lower right corner of the editor), and you can convert it as well.
This works in all chrome, IE, Firefox.
In Database > table > field type .for example set the symbol column TO varchar(2) utf8_bin
php code:
$symbol = '£';
echo mb_convert_encoding($symbol, 'UTF-8', 'HTML-ENTITIES');
or
html_entity_decode($symbol, ENT_NOQUOTES, 'UTF-8');
And also make sure set the HTML OR XML encoding to encoding="UTF-8"
Note: You should make sure that database, document type and php code all have a same encoding
How ever the better solution would be using £

I've done some research and turns out that to encode special characters we use encodeURI(component) and decodeURI.
However when I try do something like:
var my_special_char = 'ñ';
my_div.innerHTML = decodeURI(encodeURI(my_special_char))
A "question mark" is printed.
I found this (non-complete) table about special characters: http://www.javascripter.net/faq/accentedcharacters.htm
Effectively when I do
decodeURI("%C3%B1"); // ñ
it prints ñ.
But if I try with:
decodeURI(encodeURI('ñ'))
I still get a "question mark".
How does character enconding work in JS? And where can I find a really comprehensive special characters' in encodeURI format (ready out-of-the-box to be decoded via decodeURI)?
EDIT:
in my (the application is an AngularJS application) I have meta charset=utf-8 (written in the right HTML syntax as proposed in the answer, it actually comes from AngularJS' starter project)
I'm using WebStorm IDE: I checked out the settings and the enconding used is UTF-8
I'm serving the page locally in Apache (XAMPP)
EDIT 2:
as advised in the answers, I created a .htaccess file in /htdocs whose content is:
AddDefaultCharset UTF-8
as well as renaming both index.html and the view's file by adding .utf8 before .html file extension.
then I restarted Apache (from XAMPP console).
But the issue is not gone. Any clue?
EDIT 3: I finally even tried to open the file in Sublime Text 3 and save as UTF-8 file, nothing changes
You don't have to do any special encoding in your JS strings (apart for the special case of strings which may be seen as script element closing).
If your JS file encoding matches the HTTP header (most commonly UTF-8), it's decoded if you just do
var my_special_char = 'ñ';
my_div.innerHTML = my_special_char;
To help the browser, and assuming you're correctly serving the files with the relevant HTTP header (the way it's set up highly depends on your server), you should have this meta tag in you HTML header:
<meta charset='utf-8'>
If your script is in a separate file, you should also declare the encoding in the script element:
<script charset="UTF-8" src="yourFile.js"></script>
You should add <meta charset="utf-8" /> inside your head tag. In this way the browser knows which charset to use and no more question marks will appear :)
in classic notepad it solved by clicking
file > Save As > in Encoding dropdown menu > UTF-8
in notepad++ by click
Encoding > Encode in UTF-8
or by adding charset attribute into metatag charset='utf-8'
<meta charset='utf-8'>
i have an alert box which i want to show some icelandic text but its not showing it
<script>
function check() {
alert("Þú verður að vera skráð/ur inn til þess að senda skilaboð");
}
</script>
it is showing the alert box but the text is messed up :(
Þú verður að vera skráð/ur inn til þess að senda skilaboð
any help please :(
Today the web uses many international languages and has settled on using UTF-8 (a flavour of unicode) for character encoding. This is important.
You are using iso-8859-1, the MS Windows character set. If you have Word 2007 or 2010 you have the option of re-saving your text as UTF-8. If you've ever seen ????? or � instead of text on someone's web site, it's due to the wrong encoding type.
<meta http-equiv="Content-type" content="text/html; charset=UTF-8"/>
Always use UTF-8 end-to end. Do not use 8859-1 or Windows 2151 encoding.
See:
The Absolute Minimum Every Software Developer Absolutely, Positively Must Know About Unicode and Character Sets (No Excuses!)
ISO-8859-1 vs UTF-8?
Character encodings and the beauty of UTF-8
Let's do it in html5 manner :)
<!doctype html>
<html>
<head>
<meta charset = "utf-8" />
</head>
encoding hazards my best guesses:
check if...
the js-file is stored properly encoded (UTF8) on your server
the server delivers the JS file with proper encoding header (HTTP/1.1 about encoding)
... #Diodeus is right
What you see displayed by the alert is UTF-8 encoded text misinterpreted as windows-1252 encoded. (Windows-1252 is a Microsoft extension to ISO-8859-1.)
If your pages are ISO-8859-1 encoded, as they apparently are, then this applies to the script element content too. There is something odd going if the code you posted does not work. Are you sure the element is really inside a normal page of yours where Icelandic characters work OK? You should not try this fix the situation with a shot in the dark like changing encodings without knowing what is going on.
I’m just making a guess: the alert() invocation is really in an external .js file, which is UTF-8 encoded but treated by browsers as windows-1252 encoded. Then there are two alternative fixes: 1) open that file in an editor and save it as windows-1252 or ISO-8859-1 encoded; or 2) modify server settings to declared UTF-8 for .js files or (less reliably) add charset=utf-8 attribute to the script element.
Alternatively, if the alert() invocation is really inside a script element in an HTML file, then perhaps this file is really UTF-8 encoded but you don’t observe other problems because the content of the file does not otherwise contain Icelandic characters. In this case, it is best to open the HTML file in your authoring program and change its encoding to windows-1252 or ISO-8859-1.
I have a javascript script which is calling a php page to supply an ajax form with suggestions. The suggestions are returned fine by the php page, but for some reason, when i set the responsetext of the javascript object request as an element in my HTML page, all the special characters (ie. á or ã) show up as this question mark. Is there a function II must run on the response text of the request to make sure these are read properly?
Thanks.
If you are not serving your HTML pages as UTF-8, the browser will guess an encoding, typically a single-byte Windows codepage depending on the user's locale.
But this doesn't happen for AJAX. With XMLHttpRequest, unless you specifically state an encoding in the Content-Type: ...; charset= parameter, the browser will treat it as UTF-8. That means if you are actually serving Windows code page 1252 (Western European) content, you will get an invalid UTF-8 sequence and consequent question mark.
You don't want to be using a non-UTF-8 encoding! Make sure you are using UTF-8 throughout your application. Serve all your pages with Content-Type: text/html; charset=utf-8, store your data in UTF-8 tables, use mysql_set_charset() to choose UTF-8, etc.
In any case consider passing AJAX responses using JSON. The function json_encode() will create a JSON string that uses JavaScript escape sequences for non-ASCII characters, which avoids any problem of encoding mismatch. Also this is easier to extend to add functionality than returning raw HTML.
I would try, in your php script, to encode everything as html entities.
This can be easily tested by doing something like this before returning the results to javascript:
$results = htmlentities($htmlstring);
There's also the htmlspecialchars function you might try.
More about this here:
http://php.net/manual/en/function.htmlentities.php
On my website visitors can do some inline editing. I use ajax for it with a MySQL database and PHP. I expect the Dutch language to be used on the website.
My challenge is to get the character encoding to work well.
I could use advice on:
the database (do i use utf-8? latin1_swedish_ci)
the tables in the database (i'd prefer to heve them similar to the database.)
the escaping to use in the ajax call (x = escape(x);)
the webpage character set (UTF-8? ISO-something?)
how this all works together.
I use nicEdit as javascript wysiwyg editor.
I could of course explain what happens whan I want to save ë and if that helps I will, but I figured it would be best to understand the matter instead of just trying to quick-fix it.
[EDIT]
To elaborate:
I use these in my PHP
$input = stripslashes($input); //(if magic quotes are 'on')
$input = mysql_real_escape_string($input);
$input = strip_tags($input, '<strong><em><span><ul><ol><p><a><br><li>');
In my htmlpage:
<meta http-equiv="Content-Type" content="text/html; charset=UTF-8" />
Javascript:
x = excape(x);
Database:
MySQL connection collation: utf8_general_ci
Table options: DEFAULT CHARSET=utf8
This is an example of what happens:
I enter (inline) the word Rëg (using 'option+u' then 'e' on my mac).
I save the word. It shows like this: R�g on the webpage.
In the database i find Rëg.
I open the editor, do nothing but save again and it shows: R%uFFFDg in the database as well as on the page. After that it does not change anymore.
Any help is greatly appreciated.
Kim
It shows like this: R�g on the webpage.
You need to instruct the webbrowser that you're displaying the webpage in UTF-8 and that it should interpret it as the same. Add the following to top of your PHP, before emitting any character to the output:
header('Content-Type: text/html; charset=utf-8');
Only the <meta> tag is not enough. This is not used by the webbrowser. It's the response header which counts. By the way, Javascript's escape() function is deprecated.

Just use UTF-8 for everything, and normally it will just work.
I would like to change string encoding from UTF-8 to ISO-8859-2 in Javascript. How can I do it?
I need it because I've designed a widget. User just copies < script > tag from my site and puts it on his. This script creates div and puts into div widget contents with text.
If target website is in UTF-8 encoding - it works fine. But when it is in ISO-8859-2 than text that is encoded in UTF-8 is displayed on site with ISO-8859-2 and as a result I see trash.
Instead of using e.g. "ĉ" in your JavaScript code, use Unicode escapes such as "\u0109".
If you're in control of the output, you can replace all special characters with unicode escapes (e.g. \u00e4 for ä). The browser can interpret it correctly regardless of document encoding.
The easiest way to do this would be to put the string into a JSON encoder. Both PHP's and Ruby's does that. Don't know about other implementations though.
Another solution that might work is to add charset="utf-8" to the <script> tag.
I suppose you just need to convert your wdiget from UTF-8 to ISO-8859-2 and provide 2 versions of script.
