title: Euro symbol doesn't display in dompdf generated pdf
body: <p>I'm using the <a href="http://code.google.com/p/dompdf/" rel="nofollow">dompdf</a> library to generate a pdf. I need to output an euro symbol (€) but it shows just a square. I tried using both directly the symbol or the code &euro; and I'm using the font family like this:</p>
  
  <pre><code>    font-family: Arial, "Helvetica", Arial, "Liberation Sans", sans-serif;
  </code></pre>
  
  <p>And I put this in the :</p>
  
  <pre><code>&lt;meta charset="UTF-8"&gt;
  &lt;meta http-equiv="Content-Type" content="text/html; charset=utf-8"/&gt;
  </code></pre>
  
  <p>It is working fine on a Mac, but not on Linux.</p>
