I don\'t know. I did not check that how AbiWord handle display character on screen. But if we can
handle superscribe or subscribe so we can handle Multi-level displaying of Thai characters.

No. TIS-620 (Thai code) can be mapping directly to Unicode.
Please look at this homepage for more information about Thai implementation and its problem.

I think that this place is where I can put my code it. Thanks you :)

I will waiting for it.
