I need to find out the names for Unicode characters when the user enters the number for it. An example would be to enter 0041 and get given "Latin Capital Letter A" as the result.

• javascript
• unicode
• character
• codepoint

• You're going to have to construct (or appropriate) a lookup table. There's nothing built in to the language or browsers (or any server-side runtime I know of) that'll do this for you. – Pointy Commented Sep 26, 2010 at 17:00

As far as I know, there isn't a standard way to do this. You could probably parse the UnicodeData.txt file to get this information.

Here should be what you're looking for. The first array is simply http://unicode.org/Public/UNIDATA/Index.txt with replacing newlines with |;

// this mess..
var unc = "A WITH ACUTE, LATIN CAPITAL LETTER   00C1| /*... really big array ...*/ |zwsp    200B";
var uncs=unc.split("|");
var final_a = [];
var final_s = "";
for each (var item in uncs) {
    var _T=item.split("\t");
    //final_a [_T[1]] = _T[0];
    final_s += '"' + _T[1] + '"' + ' : ' + '"' + _T[0] + '",';
}

console.log (final_s);

// yields..

var unicode_lookup = { /*really big array*/ }

// which we can use like so ...

alert(unicode_lookup["1D01"]);
// AE, LATIN LETTER SMALL CAPITAL

SO doesn't preserve tabs so the first part may not work if you simply copy-paste it. You'll note that some characters are duplicates so you may want to do some cleanup.
