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: http://www.tiro.com/John/Problems_for_Indic_Typography.pdf 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.

Some of the combination you have mentioned handled in better way with existing features in Lohit and Sakal Bharati. I think font designer by considering these issues before design can help in this. http://pravins.fedorapeople.org/with-lohit.png http://pravins.fedorapeople.org/with-sakalbharati.png I am not sure for dotted circle part yet, dunno is it valid combination or not. Need input from language person for same. But i am definitely support request you have made to have consideration of glyphs inbetween cluster/syllable. It will definitely give more flexibility to font developers to develop high quality font with limited number of glyphs. I have seen such issues in lohit telugu, for below base part will provide some example. I dont think it will affect any existing font, if implement in proper way in OTLS, like enabling across cluster context only if font contain feature. In this way it will not affect existing fonts anyway. Best Regards, Pravin Satpute -------------- next part -------------- An HTML attachment was scrubbed...

The following text is not rendered correct. "\u0CB8\u0CBE\u0CAB\u0CCD\u0C9F\u0CCD\u0020\u0CB8\u0CCD\u0CA8\u0CBE\u0CAA\u0CCD" I did verify it both with 2.5.2 and 2.5.3. Is his a known issue?
