Hi Prakash,

I was finally able to look through the files you sent me. Actually, I
passed them on to Pete Townsend, but anyway...

There are a couple of problems:

* the file you have called T1V10285.CDP is actually the T1GI0361 code
page. You should rename the file T1GI0361.CDP and update the
afp-fonts.xml file appropriately.

* The code page file is ASCII encoded. The encoding attribute must be
set to an appropriate ASCII encoding in the afp-fonts.xml

Good luck,
Joe

P.S. I like to discuss these problems on the list. This allows everyone
to see what the problem was, and possible other people to suggest
solutions.
