Maybe you editor use incorrect encoding by default. Also there is possible issues if you edit in windows and then upload to Linux (a lot of hosting providers use Linux) see
http://stackoverflow.com/questions/2466728/windows-to-linux-utf-8-fileTry to play with encoding settings in different editors like Notepad++ or Adobe Dreamweawer.
Please note after you change encoding write something in your language then save. Also try to use Built-in text editor in hosting cpanel
One more thing - sometimes php - UTF-8 works on hosting A but not on hosting B
So a lot of things can cause issues
