Converting unicode character to string format

Question

Does anyone know how to convert a unicode to a string in javascript. For instance:

\\u2211 -> ∑ \\u0032 -> 2 \\u222B -> ∫

Answer 1

Just found a way: String.fromCharCode(parseInt(unicode,16)) returns the right symbol representation. The unicode here doesn't have the \u in front of it just the number.
