title: jpgraph charset problem
body: <p>I use <code>php</code> <a href="http://jpgraph.net/" rel="nofollow noreferrer">jpgraph</a> library, but there i a small problem with charsets.
  lets assume <code>graph.php</code> generates the image, and i call it from <code>some.php</code></p>
  
  <p><code>some.php</code></p>
  
  <pre><code>     ...
      &lt;meta http-equiv="content-type" content="text/html; charset=utf-8" /&gt;
       ...
      &lt;img src="graph.php" /&gt;
       ...
  </code></pre>
  
  <p>as you see, i set charsets in <code>some.php</code>, but it doesn't show the text of the graph, which is in foreign language.(maybe i must set it in <code>graph.php</code>? but how?)</p>
  
  <p>What is the problem?</p>
  
  <p>Thanks
  UPDATE</p>
  
  <p>even when i try to enter numerical HTML encoding
  of the Unicode character from <a href="http://www.utf8-chartable.de/unicode-utf8-table.pl?start=1328&amp;names=-&amp;utf8=dec&amp;unicodeinhtml=dec" rel="nofollow noreferrer">here</a>, it doesn't work for Armenia language:/</p>
