Yeah, but that is hardly enough to implement an AAT font, let alone a
rendering engine. Nor do I see from that article a reason why this is
advantageous to OpenType, something which Apple promised to support but
apparently does not adequately do so. I was approached by someone who
wanted to implement Indic fonts in AAT, and he uses a trial-and-error
method based on copying rules from existing fonts, which is a rather
laborious and error-prone method for Indic fonts. Currently, I see no
reason for the open-source world to try to support AAT.

Well, if the particular representation is still in use, the bug could
fixed. Could you submit a more complete report, including the set of
Unicode input characters, a picture of the expected output, and, if
possible, a picture of what you actually get from Pango, ICU, or QT?

It would be great if you could list these by the Unicode input
and maybe someone can take a look at them. It would be even better if
would be willing to help out in putting together a comprehensive set of
conjuncts, and a complete glyph repository for Tamil.
