console.log('\u00B0'); // outputs ° in my chrome console

so basically: '\u00B0'

This is how it is done. [MDN - Values, Variables and Literals: Unicode escape sequences](https://developer.mozilla.org/en/JavaScript/Guide/Values,_Variables,_and_Literals#Unicode_escape_sequences).

The problem with this approach is that a string `'00B0'` can't easily be converted into a string `'\u00B0'`. The string literal `'\u00B0'` is a single character, but `'\u' + str` doesn't work to produce that. You would need to create code for the string literal and then execute the code to get the string. – Guffa May 01 '15 at 16:22

Parse the string into a number to get the character code, then use the String.fromCharCode method to create a string from it:

var degreeSign = String.fromCharCode(parseInt(str, 16));

Thanks, Now I have String that contain certain special character(in Unicode string). How can i decode it. E.g var str = "002E002C002D0021003F0040007E005F000A005C002F002600220027003B005E007C003A00280029003C007B007D003E005"; any idea ? please... – Paresh Thummar Apr 11 '12 at 11:57
@PareshThummar: Take four characters at a time from the string and parse them as above: http://jsfiddle.net/Guffa/DXf3R/ – Guffa Apr 11 '12 at 12:12

You can use Unicode characters in HTML by following this example

&#x00B0;

The degrees sign will appear like so: °

edit: Except this question is tagged as Node.js. What is the purpose of getting the symbol? Is it front-end or back-end?

If you're sure your string is well formed, you could also do it like this:

var degreeSign = eval("('\\u" + str + "')");
