title: Converting UTF8 text for use in a URL
body: <p>I'm developing an international site which uses UTF8 to display non english characters. I'm also using friendly URLS which contain the item name. Obviously I can't use the non english characters in the URL.</p>
  
  <p>Is there some sort of common practice for this conversion? I'm not sure which english characters i should be replacing them with. Some are quite obvious (like è to e) but other characters I am not familiar with (such as ß).</p>
