title: Wrong symbols in PHP exception
body: <p>When I catch an exception during my PHP script, the sentence is well displayed. But specials characters like é,à,è are replaced with wierd symbols.</p>
  
  <p>In the beginning of my PHP script I have <code>header('Content-Type: text/html; charset=utf-8');</code></p>
  
  <p>I also tried to set <code>&lt;meta charset="UTF-8"&gt;</code> in my html.</p>
  
  <p>Any idea ?</p>
