javascript - 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 -> ∫

I basically want to be able to display the symbol in xhtml or html. Haven't decided which I will be using yet.

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.
