ODPOWIEDZ! - Türkçe

Hi there. I'm having problems with the turkish letters. I use ASCII Codes for all the letters my keyboard doesn't have. It works fine for spanish and swedish, look -> å Å ñ Ñ

And it also works for ç Ç and I

BUT it won't work for S s G g and i (without the dot).
Why is that? The ascii must be true, otherwise ç wouldn't work as well.

I know it is possible to change the keyboard, but it would be very inconvenient since i learn multiple languages.
Basically i know how to spell a word, but i cannot show you because i can't type it. Annoying!

Do you have any solution? Tesekkür ederim.
