title: Display character with unicode code
body: <p>I use a custom font to display icons. Each icon is a character.</p>
  
  <p>I can use them in UIControls by copy/pasting the character like this: </p>
  
  <pre><code>myLabel.text = @"";
  </code></pre>
  
  <p>Or with the unicode hexadecimal code: </p>
  
  <pre><code>myLabel.text = [NSString stringWithUTF8String:"\uf000"];
  </code></pre>
  
  <p>Or </p>
  
  <pre><code>myLabel.text = [NSString stringWithFormat:@"%c", 0xf000]
  </code></pre>
  
  <p>Now I'm trying to make it more dynamic with the characters hexadecimal codes stored in a dictionary as a NSString:</p>
  
  <pre><code>NSString *glassIcon = [charactersList objectForKey:@"icon-glass"]; //glassIcon = f000
  </code></pre>
  
  <p>But I can't achieve to display this character in my label.</p>
  
  <p>I tried</p>
  
  <pre><code>myLabel.text = [NSString stringWithFormat:@"%s", [subString UTF8String]];
  </code></pre>
  
  <p>or</p>
  
  <pre><code>myLabel.text = [NSString stringWithUTF8String:[subString UTF8String]];
  </code></pre>
  
  <p>But none of this work.</p>
  
  <p>I'm sure I'm missing something obvious but I can't find out.</p>
