Can anyone clarify this one:
In Microsoft page here :
http://www.microsoft.com/typography/OTSPEC/indicot/default.htm
says Malayalam chillu glyphs are formed when inputting
(consonant)+(virama). Can I use another formation for chillus, I
want to use (consonant)+(virama)+(ZWJ) any problem?
And any problem, If I am am giving ligature formation in this
way
in OpenType tables?
Regards,
Baiju M
