title: Valid font-family names
body: <p>I've made some research and I found this <a href="https://developer.mozilla.org/en-US/docs/Web/CSS/font-family" rel="nofollow">article</a>, but it doesn't completely help me. I am interested in what are valid characters that can be used for naming font families. Theoretically, can I use every character for naming, just by putting everything in quotation marks? How is with naming in practice?</p>
  
  <p>Example:</p>
  
  <pre><code>@font-face {
          font-family: '&amp;This is my font 1234#!&amp;&amp;&amp;';
          src: url('font.eot');
          src: url('font.eot?#iefix') format('embedded-opentype'),
               url('font.woff') format('woff'),
               url('font.ttf') format('truetype');
          font-weight: normal;
          font-style: normal;
  }
  </code></pre>
  
  <p>I would also want to know if there are some standards, conventions used for naming font families? </p>
