Please describe the problem:
Tamil indic-fonts are not being displayed properly in gnome-terminal/gedit when
entered with tamil language interface (via gdm):

The "dot", the "o" and "oo"s to characters get displaced separately and don't
represent the actual Tamil character.

On the other hand, if I enter into English language interface (via gdm) and use
Tamil unicode keyboard, I am able to key in Tamil language characters properly:

I am currently using Ubuntu Dapper Beta on x86 IBM T41.

Steps to reproduce:
1. Install Tamil language support, ttf-indic-fonts in Ubuntu Dapper Beta
2. Login to gdm by selecting Tamil language
3. Change keyboard to Tamil unicode, open vi on gnome-terminal or gedit and
start typing.


Actual results:
The Tamil characters displayed are not actually what unicode represents.

Expected results:
For characters have two input key-sequences, the characters will change
accordingly as per the actual, original unicode form:

Does this happen every time?
Yes.
