having problem with locales ?

["Mehmet Fatih Akbulut" <mfatihakbulut@gmail.com>]

hi all,
which locales should i select to see characters like ı,ş,ç,ö,ğ,ü correctly on konsole ?
en_US UTF-8 doesnt show them right :'(
an example output of a php code: [in english: file successfully opened and then closed.]
>Dosya başarı ile açıldı ve kapatıldı. > which is what i want to see.
>Dosya baÅarı ile açıldı ve kapatıldı. > which is what i see now ...
O.S. and all installed programs are in english [so i dont want to switch locales to tr_TR], but sometimes i need the above native characters.
what should i do to see such characters correctly ?
many thanks in advance.

Cheers,
MFA
