Description Sukhjinder Sidhu 2004-12-16 21:56:36 EST
From Bugzilla Helper:
User-Agent: Mozilla/5.0 (Windows; U; Windows NT 5.1; en-GB; rv:1.7.5)
Gecko/20041110 Firefox/1.0

Description of problem:
Please note that I extracted the contents of the RPM on a Windows
machine and found these problems.  HOWEVER, this should not effect the
nature of the issues with this font.

The main issue is that it does not implement 'pstf' to create a
post-base form of Ya when entering Virama + Ya.  See TUS 4.0, ch9, p235.

Also, two simple additions of Adak Bindi and Visarg at U+0A01 and
U+0A03 would enable Unicode 4.0 support for the font.

Version-Release number of selected component (if applicable):

How reproducible:

Steps to Reproduce:
1. Enter Cons + Virama + Ya

Actual Results:  You will see the full form of Ya with a Halant (Virama).

Expected Results:  Post-base form of Ya.

Comment 1 Sukhjinder Sidhu 2004-12-16 21:58:37 EST
Looking at the font in FontLab shows that Lohit Punjabi includes the
glyph for post-base Ya, but it just isn't implemented.
Comment 5 Leon Ho 2005-03-22 08:21:58 EST
Aman has posted seperate problem to bug 151630
Comment 6 Leon Ho 2005-06-20 00:07:15 EDT
This should be fixed in FC4. Please confirm.
Comment 7 Sukhjinder Sidhu 2005-06-20 10:44:38 EDT
Nope none seem to be fixed.

Post-base Ya is not working nor are U0A01 and U0A03 added to the font.
Comment 9 Lawrence Lim 2005-09-05 20:54:42 EDT
Through the comment from Aman, this bug still exist as the new font package
still cant reproduce post-base Ya. (k + d + /) is the keystroke used.

The rest of the bugs in Comments will be split into individual bug reports.
