title: Special characters not displaying properly on Firefox
body: <p>I'm using Google font 'Pt Sans' which works on both Chrome and Safari, but on Firefox character accents are displayed after their respective letter (äåö).</p>
  
  <p>I have ensured that latin-ext is enabled and running, have double-checked that the correct font is being called and have run through the related css to see if I have done anything odd but can't find any abnormalities.</p>
  
  <p>The accent takes the same amount of horizontal space as the letter that it belongs to, but to the right of that letter - hovering over nothingness.</p>
  
  <p>Are there any known rendering issues with PT Sans? Or is this perhaps a Google fonts / Firefox compatibility issue? Any clues to what I might have missed are appreciated. Thanks.</p>
