How to create UTF characters dynamically with JavaScript

Question

I'm trying to use a variable and \u to create an UTF character with Node.js.

var code = '0045';
console.log('\u0045', '\u' + code);

But the output becomes

E u0045

How do I make it

E E

How do I create the character and store it in a variable?

Why don't you use `String.fromCharCode(n)`? See https://developer.mozilla.org/en/JavaScript/Reference/Global_Objects/String/fromCharCode — Elian Ebbing, Mar 30 '11 at 20:59

Use String.fromCharCode:

String.fromCharCode(0x0045)
String.fromCharCode(parseInt('0045', 16))
