title: How do you use font forge to generate a font?
body: <p>If you want a basic hello world font such as</p>
  
  <pre><code>&lt;html&gt;
  &lt;head&gt;
      &lt;title&gt;&lt;/title&gt;
      &lt;style type="text/css"&gt;
          @font-face {
              font-family: font1;
              src: url('http://www.w3schools.com/cssref/Sansation_Light.ttf')
              ,url('http://www.w3schools.com/cssref/Sansation_Light.ttf');
          }
          .myfont{
              font-family: font1;
              font-size: 500%;
              color: red;
          }
      &lt;/style&gt;
  &lt;/head&gt;
  &lt;body&gt;
      &lt;span class="myfont"&gt;aA&lt;/span&gt;
  &lt;/body&gt;
  &lt;/html&gt;
  </code></pre>

  <p>I want to export a .ttf file but font forge is not allowing that to happen. <a href="http://www.high-logic.com/font-editor/fontcreator/download.html" rel="nofollow noreferrer">This one</a> forces you to pay $80 before you can test it and <a href="http://ptf.com/.ttf/.ttf+creator/" rel="nofollow noreferrer">many like this</a> are probably viruses. </p>
