title: Search for multi language support chosen.js
body: <p>I want to search bar execute all words. Include Turkish letters (Ö, Ç, İ, Ş, Ğ, Ü). How can i expand chosen search bar for these words?</p>
  
  <p>For example: i'll search "istanbul" but it say can't found "İstanbul" because "i" is lowercase.</p>
  
  <p>How can i fix that?</p>
