title: Ignoring diacritic characters when comparing words with special characters (é, è, ...)
body: <p>I have a list with some Belgian cities with diacritic characters: (Liège, Quiévrain, Franière, etc.) and I would like to transform these special characters to compare with a list containing the same names in upper case, but without the diacritical marks (LIEGE, QUIEVRAIN, FRANIERE)</p>
  
  <p>What i first tried to do was to use the upper case:</p>
  
  <p><code>LIEGE.contentEqual(Liège.toUpperCase())</code> but that doesn't fit because the Upper case of <code>Liège</code> is <code>LIÈGE</code> and not <code>LIEGE</code>.</p>
  
  <p>I have some complicated ideas like replacing each character, but that sounds stupid and a long process.</p>
  
  <p>Any ideas on how to do this in a smart way?</p>
