title: Unicode via CSS :before
body: <p>I am using <a href="http://fortawesome.github.com/Font-Awesome/" rel="noreferrer">Font Awesome</a> on my webpage and I want to display an icon inside the <code>:before</code> pseudo element.</p>
  
  <p>According to the <a href="http://fortawesome.github.io/Font-Awesome/cheatsheet/" rel="noreferrer">documentation/cheatsheet</a>, I have to type <code>&amp;#xf066;</code> to get this font, but it isn't working. I believe that is normal because HTML entities aren't supported in <code>:before</code>.<br>
  So I googled a bit and found out, that if you want to display HTML entities in <code>:before</code>, you have to use the escaped hex reference.<br>
  So I was searching for the hex reference to <code>&amp;#xf066;</code> but I found nothing. I believe that is because these are "private use" values, whatever that means.</p>
  
  <p>Is there any way to get it working in <code>:before</code>?</p>
