Message from OpenType list:


Back in August, there was a discussion on the OpenType developer list
(subject: '<init> and <fina> in Indic scripts?') regarding Indic shaping
engines limiting layout input and context to individual clusters,
preventing contextual interaction across syllable boundaries. Although
some concerns were raised about possible impact on existing fonts if
this behaviour were to change, I believe this is a minor an unproven
concern vs. the clear problems raised for Indic typography by this
limitation.

I have prepared a discussion paper -- i.e. a paper to prompt discussion
-- illustrating some of the problems that occur in Indian typography
that cannot be resolved without cross-cluster layout interaction. This
paper is available here:

Although I will likely draw attention to this paper in other forums, it
would be helpful if discussion were conducted on the OpenType developer
list.
