title: UILabel to display Emoji emotions rather than their unicode values \ueXXXX
body: <p>I'm retrieving values from a server in XML format, the server sends the following string:
  "This is a nice string with Emoji \ue056\ue056\ue056\ue057\ue057\ue056\ue056"</p>
  
  <p>I have been struggling to make my UILabel display the emoji icons rather the following</p>
  
  <p>\ue056\ue056\ue056\ue057\ue057\ue056\ue056</p>
  
  <p>I have tried </p>
  
  <pre><code>[chatText setText:[chatString stringByReplacingOccurrencesOfString:@"\\\\u" withString:@"\\u"]];
  </code></pre>
  
  <p>Not much luck. Being desperate I have done the following:</p>
  
  <pre><code>[chatText setText:[[chatString cStringUsingEncoding:NSNonLossyASCIIStringEncoding] stringByReplacingOccurrencesOfString:@"\\\\u" withString:@"\\u"]];
  </code></pre>
  
  <p>Note: Assigning the following string does the trick:</p>
  
  <pre><code>[chatText setText:@"\ue056\ue056\ue056\ue057\ue057\ue056\ue056"];
  </code></pre>
