Aloha, Ken:

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.

"Digital Dharma"

July issue.

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....]

Thanks again.
