title: Doesn't show supported letters
body: <p>I'm using <a href="http://www.google.com/fonts/specimen/Signika" rel="nofollow noreferrer">Signika Bold</a> as font for my headers. Font is loaded from Google Webfonts. As you can see in <a href="http://jsfiddle.net/vule/6rdj6/" rel="nofollow noreferrer">the demo</a>, there is a problem with showing letter "Č", both upper and lower case. The letter is on the list of supported fonts on the official Webfonts page.</p>
  
  <p><img src="https://i.stack.imgur.com/WlcGU.png" alt="enter image description here"></p>
  
  <p><strong><em>CSS:</em></strong></p>
  
  <pre><code>@font-face {
     font-family: "Signika";
     font-style: normal;
     font-weight: 700;
     src: local("Signika-Bold"), url(http://themes.googleusercontent.com/static/fonts/signika/v3/7M5kxD4eGxuhgFaIk95pBRsxEYwM7FgeyaSgU71cLG0.woff) format("woff");
  }
  
  h1 {
     font-family: "Signika", Helvetica, sans-serif;
  }
  </code></pre>
  
  <p>I have also tried typing the letter as HTML entitle (<code>&amp;#269;</code>), but it doesn't help.</p>
