I installed the turkish t9 file and everything is working.
But I have two questions. I was checking the xml file in the cab, and realized that one registry entity is written as "avalible" where it should be "available" under HKLM\T9 Input Method\MUI\Languages.
I was wondering if that is a problem and whether we need to fix it or not. I also checked the english cab file and it has the same problem.
Now, my second problem is weird. I am using turkish t9, but turkish has characters which do not exist in english. When I create an sms with turkish characters, 1 sms is worth 70 characters. normally if I don't use any turkish special characters, it is 160 characters. You can see that, I prefer to replace those special characters with english equivalents when I write sms messages.
So the second question is, is there a way to edit the dictionary of the turkish t9 file? If I could replace all special characters with their english equivalents, I would be a happy man
