Subject: [patch]: fixing Malayalam rendering issues Ref:#403404

Date: Thu, 28 Dec 2006 02:45:06 +0530

[Message part 1 (text/plain, inline)]

Package: libpango1.0-0
Version: 1.14.8-3
Severity: important
X-Debbugs-CC: debian-in-workers@lists.alioth.debian.org,
indlinux-group@lists.sourceforge.net


I am one of the Malayalam language co-ordinators for debian installer.
Refering to bug Ref:#403404 reported at debian.org by Davide Viti
<zinosat AT tiscali.it> we had faced some incorrect rendering for the
language "Malayalam" (code ml) and it seems to be caused by some
recent changes to pango. The language has already been activated in
the graphical installer of debian currently in testing (etch). But for
it to be usefull as a supported language on the debian installer these
rendering issues that have been visible needed to be fixed.

These bugs were introduced by a previous patching of pango by Rahul
Bhalerao and LingNing Zhang to fix bugs in lohit_ml font for Fedora
Core 6. Debian malayalam team have been working on these issues for
some days now and we have been meeting, fixing and testing some of the
major rendering issues that will hinder the language support for etch.
We had met  yesterday (26th) and finalized some of the obvious fixes
that are necessarily required. We also finalized a patch and it is
attached herewith. Some of the major fixes that have been patched are
mentioned here

* Removed Cons+0d4d+RA(0d30)/RRA(0d31) +KA(0d15)/HA(0d39) exception
and moved 0d30 from _cn form back to its intitial _pb form
* Correct rendering for ZWJ (SF_PROCESS_ZWJ is removed from the flags
for malayalam)
* Fixing the rendering of LA (changed to _bb from _ct)

(We stiil have some more issues to solve)

The patch is submited upstream http://bugzilla.gnome.org/show_bug.cgi?id=357790

We know that the pango code for etch has been frozen but since the
fixes are only specific to malayalam and it is a major fix we request
you to include it, as it is critical for correct rendering support for
Malayalam in graphical installer and other pango based applications.
This will be a crucial for malayalam support for IT@School project,
the largest debian installtion (total 2666 schools and more than 25000
computers) in the world.

Regards
Praveen
