I have search area(edittext) and a list of bus stops. When a character is entered, the list is filtered simultaneously.

There are bus stops including Turkish characters like "beşiktaş". I want the list to show me "beşiktaş" when I entered "besiktas".

I have all data (many turkish charactered data) on server database and there are approximately 5500 bus stops. So I can't do casting on mobile devices because of insufficient RAM.
