Outlook 2003 problem.

I use Outlook 2003 on XP and Vista.
On my website I also use a Form Mail designed by Mike Cherim, Gbcf-v3. Absolutely wonderful form mail.

When I receive some emails, typed by Turkish keyboard, characters like ç ğ ı ö ş ü are totally unreadable.

First I thought it was the form mail giving me this problem but after some investigation I realized that it was Outlook 2003 was the culprit.

Tried to change the options/mail format/international settings but no veil.

Has anyone come across a problem like this? Can you help me at all please?

PS: I am not sure if I am allowed to write my website address.
