Charactor set issue

[afridy]

Hai friends,
My mysql db have various countries charactors.
Fow, English, German, french, etc working fine.
but i added some turkish charactors. it only shows a ? mark for some of the turkish charactors.

php my admin shows the following settings for my db :-
MySQL charset: UTF-8 Unicode (utf8)
MySQL connection collation : UTF8_General_ci

Now what i should do to get the Turkish charactors exist on the same table like other language charactors exist ?
