title: Issues rendering characters with diacritics of custom font
body: <p>I have installed a custom font and have tried to render an attributed string created with it using 2 methods:
  1. Use a CoreText CTFrame to draw the string
  2. In iOS6, using drawing the attributed string directly into the graphics context.</p>
  
  <p>Both methods yield the same issue with characters containing diacritics see attached image (character appears "bold"). I have loaded the same text into a UILabel and the characters displays normally, which rules out any issues with the font itself.</p>
  
  <p>Any advice how this can be fixed would be greatly appreciated please.<img src="https://i.stack.imgur.com/J2jiJ.png" alt="enter image description here"></p>
