Tamil character "க" in missing in Tamil99 supplied with Mac OS X 10.5
I want to use Tamil99 to write in Tamil language. But when i try to do that, i found that the character "க" is missing. If type "க" it shows "ஹ" instead. I try to check in the keyboard viewer there i can see "ஹ" character assigned to two key. Is it in my macbook only? Can you guys pl check yours and help me to fix this.
Thanks.
MacBook 2.2GHz, Mac OS X (10.5.5)
