setting textarea with special characters - won't render them

[andymilk]

Greetings!

I'm using a dropdown to set the value of a textarea to some text pulled
from a database.

This text is something like this:

单元

When I use a simple "document.write", it displays the characters
perfectly. When I set the textarea value to the same text, it shows
the "单元" instead.

Is there some sort of Javascript encoding I'm supposed to set?

Any help would be much appreciation.

Thanks,
Andy

Based on a Mike Winter post[1], the following should do the trick:
function replaceCharCodes(str)
{
return str.replace(/&#(\d+);/g,
function() {
return String.fromCharCode(arguments[1]);
});
}
e.g.

alert(charCodeToString('Üfooá bar Õ'));

May not be supported by some browsers, particularly older ones.

Agghh...

alert(replaceCharCodes('Üfooá bar Õ'));
