title: iOS Font Not Properly Displaying All Unicode Characters
body: <p>Example of two characters: U+22FF, U+23BA... and many others.</p>
  
  <p>Is this an encoding layer that I'm misunderstanding for iOS? Like, at some point it no longer can properly display codes beyond 22B...?</p>
  
  <p>I'm capturing this in an NSString, and trying to simply update a text field. Something like</p>
  
  <pre><code>NSString *test = @"\u23ba";
  [displayText setText:test];
  </code></pre>
  
  <p>This will display a standard type error like a box with a question mark in it, or just a box (depending on the font). </p>
  
  <p>Is there a way to expand the unicode options for iOS? Because these can be displayed on my Mac. Or, is my only option some variant of the NSAttributableString route?</p>
