title: sitemaps url encoding
body: <p>What's the encoding I should use when generating site maps for google?
  I'd like to have urls like:</p>
  
  <pre><code>example.com/supplì-rome
  </code></pre>
  
  <p>rather than:</p>
  
  <pre><code>example.com/suppl%C3%AC-rome
  </code></pre>
  
  <p>not sure whether <a href="http://support.google.com/webmasters/bin/answer.py?hl=en&amp;answer=35653" rel="nofollow">google</a> requires the second form or not.
  I'd like users to share nice links like in the first case.
  I'm using Zend Framework router to handle nice links</p>
