title: Emoji Unicode for IOS and Android - IOS SDK
body: <p>I want to customize the emoji i want to show at iphone foe chat messanger.
  I got existing application for android, I discover unicode for IOS and Android id different.</p>
  
  <p>Such as string as below (from android):
  \ud83d\ude25\ud83d\ude1e❤\ud83d\ude2d</p>
  
  <p>when I replace the unicode android to ios, I got the string as below:
  \ue401\ue058❤\ue411</p>
  
  <p>Then I convert to ASCII unicode with the code as below:</p>
  
  <pre><code>NSData *data1 = [tmp
                   dataUsingEncoding:NSUTF8StringEncoding];
  
  NSString *emojiStr = [[NSString alloc] initWithData:data1 encoding:NSNonLossyASCIIStringEncoding];
  </code></pre>
  
  <p>Then I will get the null for emojiStr.
  Can anyone help what is the wrong with my code?</p>
  
  <p>Thanks</p>
