title: Converting unicode character to string format
body: <p>Does anyone know how to convert a unicode to a string in javascript. For instance:</p>
  
  <p><code>\u2211 -&gt; ∑</code>
  <code>\u0032 -&gt; 2</code>
  <code>\u222B -&gt; ∫</code></p>
  
  <p>I basically want to be able to display the symbol in xhtml or html. Haven't decided which I will be using yet.</p>
