title: Rect Transform position of an individual letter ( char ) in Unity UI
body: <p>Is it possible to get the position of an individual char in a string in Unity? </p>
  
  <p>So if I had a block of text like: <strong>"I want a button here @"</strong> </p>
  
  <p>I could place an object ( like a button! ) where the @ symbol is.</p>
  
  <p>many thanks...</p>
