title: How do I remove "\U0000fffc" from a string in Swift?
body: <p>I have added an image to a textfield, and wish to remove it again. I've tried the following two lines to no avail?</p>
  
  <pre><code>string = string.stringByReplacingOccurrencesOfString("\\U0000fffc", withString: "", options: NSStringCompareOptions.LiteralSearch, range: nil)
  string = string.stringByReplacingOccurrencesOfString("\U0000fffc", withString: "", options: NSStringCompareOptions.LiteralSearch, range: nil)
  </code></pre>
  
  <p>Any help would be greatly appreciated, thanks so much!</p>
