title: Replace occurrences of NSString - iPhone
body: <p>I have a long NSString in which I m trying to replace special characters. Part of my string looks like this:</p>
  
  <pre><code>"veau (c\u00f4telette)","veau (filet)","agneau (gigot)","agneau (c\u00f4telette)","b**\u0153**uf (hach\u00e9)","porc (hach\u00e9)"
  </code></pre>
  
  <p>I would like to replace all the \u0153 with "oe". I've tried:</p>
  
  <pre><code>[response stringByReplacingOccurrencesOfString:@"\u0153" withString:@"oe"];
  </code></pre>
  
  <p>but it doesn't work.... I don't understand why!</p>
