The Search implementation does not support Turkish Character

Hi you add a new implement: Search View. This is  a good idea. But The Search implement does not support some Turkish character ( ı-I ; ğ-Ğ ; , ş-Ş) . How can I  add this characters ? 

And one more question? How can I re-create dictionary and wikipedia content? Because I think the dictionary does not support Turkish and unfortunately wikipedia does not available for my country. 

Thanks.
