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

A function from k.ken's response:

function unicodeToChar(text) {
   return text.replace(/\\u[\dA-F]{4}/gi, 
          function (match) {
               return String.fromCharCode(parseInt(match.replace(/\\u/g, ''), 16));
          });
}

Takes all unicode characters in the inputted string, and converts them to the character.
