international characters in Javascript

javascript unicode internationalization character-encoding

Solution 1

Just specifying UTF-8 in the header is not enough. I'd bet you haven't saved your file as UTF-8. Any reasonably advanced text editor will have this option. Try that and I'm sure it'll work!

Solution 2

If you ever can't set the response encoding, you can use \u escape sequence in the JavaScript string literal to display these characters.

alert("\u00e6\u00f8\u00e5")

Solution 3

You can also use String.fromCharCode() to output a character from a numeric entity.

e.g. String.fromCharCode( 8226 ) will create a bullet character.

Solution 4

I get "æøå" for the first one and some junk characters for the next. Could it be that the javascript is not mangling (or mojibake) your letters but the alert dialog uses the system default font, and the font is incapable of displaying the letters?

Solution 5

I use the code like this with Thai language. It's fine.

$message is my PHP variable.

echo("<html><head><meta charset='utf-8'></head><body><script type='text/javascript'>alert('" . $message . "');</script></body></html>");

Hope this can help. Thank you.

(I cannot post image of what I did as the system said "I don't have enough reputation", so I leave the image, here. http://goo.gl/9P3DtI Sorry for inconvenience.)

Sorry for my weak English.

I am working on a web application, where I transfer data from the server to the browser in XML.

Since I'm danish, I quickly run into problems with the characters æøå.

I know that in html, I use the "&aelig;&oslash;&aring;" for æøå.

however, as soon as the chars pass through JavaScript, I get black boxes with "?" in them when using æøå, and "æøå" is printed as is.

I've made sure to set it to utf-8, but that isn't helping much.

Ideally, I want it to work with any special characters (naturally).

The example that isn't working is included below:
```
<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01//EN" "http://www.w3.org/TR/html4/strict.dtd">
<html>
  <head>
    <meta http-equiv="Content-Type" content="text/html; charset=utf-8" />
    <title>Untitled Document</title>
        <script type="text/javascript" charset="utf-8">
            alert("&aelig;&oslash;&aring;");
            alert("æøå");

        </script>
    </head>
    <body>
    </body>
</html>
```
What am I doing wrong?

Ok, thanks to Grapefrukts answer, I got it working.

I actually needed it for data coming from an MySQL server. Since the saving of the files in UTF-8 encoding only solves the problem for static content, I figure I'd include the solution for strings from a MySQL server, pulled out using PHP:

utf8_encode($MyStringHere)
