title: Accented chars not indexed properly on Android
body: <p>I have an Android app that shows an alphabetically ordered list of names. In spanish there are some names that starts with an accented character.</p>
  
  <p>My implementation of AlphabetIndexer orders in this way:</p>
  
  <p>A
  B
  C
  D
  E (regular ordering)
  ..............
  Á É ... (accented chars at end)</p>
  
  <p>I don't want this ordering, i want not to discriminate names starting with accented chars (eg. index all words starting with á in the same section as regular a). I noticied that android stock contacts app does this well, but i've diving into the code and can't find anything interesting</p>
