title: Normalize unicode
body: <p>Let's say I have document indexed with Apache Solr that contains this string: </p>
  
  <blockquote>
    <p>Klüft skräms inför</p>
  </blockquote>
  
  <p>I want to be able to find it with search using this keyword (note the "u"-"ü"):</p>
  
  <blockquote>
    <p>kluft </p>
