title: CSS bug with umlauts (äöü) using @font-face
body: <p>I have integrated wf_SegoeUILight as a font into my website <a href="http://goo.gl/Ae4VK" rel="nofollow noreferrer">goo.gl/Ae4VK</a>. However in my umlauts <strong>äöü</strong> it displays the font incorrectly. Any idea what I am doing wrong here?</p>
  
  <p><strong>Here is the incorrect umlaut "ü"</strong>

  <p><strong>The original from Microsoft looks pretty good</strong></p>
