Oh! Now I have started learning Telugu also. ;-)

Yes, the same sequence we use for Hindi also. But as U
mentioned Vattu, I thought that U mis-spelled it :-)

After discussing these issues with one of my colleague here
who knows telugu, I have come to know that
VowelSignVocalicR (which is an exception in vowel signs)
actually follows Ka. So I think actual reordering should be

   Sa Ka Halant VowelSignVocalicR

I still don't understand why you are reordering
VowelSignVocalicR before Ka and not after it. After
reordering, position of the glyphs matches with their
visual order. As you said, VowelSignVocalicR should be
displayed after Ka and hence it should also be reordered
like that. You should swap position of all matras except
VocalicR with half form.

This is what my friend here at NCST has explained me. Now I
can understand whatever you have explained above.
