title: String vs byte array representation
body: <ol>
  <li><p>I would like to know which representation of a String (normal String or byte-array) would require more memory to be stored?</p></li>
  <li><p>A byte-array representation is available to me in my code. Should I convert this to a String before transferring it over the network (in response to an AJAX call)?</p></li>
  </ol>
