You are a jewel: all questions answered, exactly what's needed... thank
you. Unicode will be featured on the back page of Hinduism Today as
one of four picks for this pages which is called.
Yes, i can do that hex to dec conversion... knowing that there is an
exactly correspondence between the integer position of the code point
and the decimal number.
Of course, acknowledged that in actual usage the ordinal position in
the series has little to do with real alpha collation except incidently
as some alphabets were entered in their "indigenous" ordinal sequence.
[This happens to be one of the "pet peeeves" of the Tamils, that the
unicode series for Tamil is out of order....]
