I think it is necesary to include chillu~
letters in unicode standared.
(Consider input mechanism, internal representation
of font and font display characteristics, will explain
my ideas later)

Whom should we contact at first? directly Ministry
for Information Technlogy or any body here (kerala).

Pavanaja, Can you help us for this (I think kannada
has done some changes in unicode by your
group effort).

We have to make this fast, because without
standardization Malayalam computing
will not be possible in its complete range.

Regards,
Baiju M
