title: Is it possible to use SF Symbols outside of UIImage?
body: <p>I'm confused on how to use SF Symbols in text in an iOS project. I have a UIButton that uses a symbol just fine using <code>UIImage systemImageNamed:</code>. I would like to display a message about that button with some text in another view. I thought I should be able to use the Unicode reference to that symbol, but it doesn't render. My understanding is that these symbols are in the Private Use Area, but I cannot get them to render using code like <code>@"Press the \U0010057C button."</code></p>
  
  <p>I have tried importing the SFSymbolsFallback.ttf font file into my project.</p>
  
  <p>I would expect to see the symbol rendered, but I get a ? instead.</p>
