title: CSS @font-face with a number
body: <p>I've narrowed down the problem to any font that has the file with a number, but I cannot figure out a solution without renaming the file.</p>
  <p>So for example <code>0 font.ttf</code> will not work while <code>font.ttf</code> works perfectly fine.</p>
  <p>My attempts, none of which successful:</p>
  <pre class="lang-css prettyprint-override"><code>@font-face {
    font-family: &quot;0 font&quot;;
    src: url(&quot;0 font.ttf&quot;);
  }
  </code></pre>
  <pre class="lang-css prettyprint-override"><code>@font-face {
    font-family: 0 font;
    src: url(0 font.ttf);
  }
  </code></pre>
  <pre class="lang-css prettyprint-override"><code>@font-face {
    font-family: &quot;\0 font&quot;;
    src: url(&quot;\0 font.ttf&quot;);
  }
  </code></pre>
  <pre class="lang-css prettyprint-override"><code>@font-face {
    font-family: \0 font;
    src: url(\0 font.ttf);
  }
  </code></pre>
