title: French characters with rewrite rule
body: <p>I have categories name in my database, and some of theme have french characters like é è ê.
  It works as desired until today when I tried to add another character à to it then I started getting SERVER ERROR</p>
  
  <p>Here is my .htaccess:</p>
  
  <pre><code>Options +FollowSymlinks
  RewriteEngine on
  RewriteRule ^([A-Za-z0-9éèêà_-\s]+)-(\d+)\.htm$   classified.php?id=$2 [L]
  </code></pre>
  
  <p>As you can see, it works fine without the à.</p>
  
  <p>How do I add that thing into the regex ?</p>
