TOPIC: turkish language problem

In turkish language file, some of characters are wrong. For example, it says "yanl1_t1r" instead of "yanlıştır". Because of this, it shows characters of words until there is a turkish character.

When I try to change and edit language file, my site is gone. My site and sql charset is "iso-8859-9", not utf-8. What can I do for this? Is the language file was encoded with utf-8? (Even so, I tried to edit it with making it utf-8, but still it didn't work properly)

What program did you use for edting it?

First I tried to edit it with Notepad2, but my site was gone.
Then I edited with Crimson Editor, which is able to encode utf-8 (with BOM), but it still had some problems.
Now I don't know what to do

try it please with PSPad www.pspad.com/en/

Yeah, it works! Thank you very much
