title: Convert route with dynamic parts to string
body: <p>I have a dynamic route in Play 2.2.2 that spans several <code>/</code></p>
  
  <pre><code>GET /file/*fileName     Controllers.Application.download(fileName)
  </code></pre>
  
  <p>What's the best way to convert <code>fileName</code> into a non URI encoded, regular string. That is, without %20 for spaces etc?</p>
