title: Content type beside text/html
body: <p>You probably all know the tag:</p>
  
  <pre><code>&lt;meta http-equiv="Content-Type" content="text/html; charset=UTF-8" /&gt;
  </code></pre>
  
  <p>I was wondering what values are there beside <code>text/html</code> for the <code>content</code> attribute?</p>
