Description A S Alam 2007-05-03 18:24:04 UTC
+++ This bug was initially created as a clone of Bug #206246 +++


Description of problem:
In some words, where the letter (say A) from the combination - (U+0d38) + (0d4d)
+ (0d31) + (0d4d) + (0d31) is used
after the Chillu consonants*, when the vowel (U + 0d4b) is used along with, this
is applied for the chillu conjunct also. This is wrong as the vowel (U + 0d4b)
is to be only applied to A.

How reproducible:

Steps to Reproduce:
(explaining with an example)
1.Open gedit
2.type any chillu consonant*, eg: (U+0d28) + (U+0d4d) + (U+200d)
3.type (U+0d38) + (0d4d) + (0d31) + (0d4d) + (0d31)
4.type any vowel (U+0d48),(U+0d4A),(U+0d4B) or (U+0d4C)
Actual results:
when step 4 is done, the vowel is applied for Chillu consonant* also.

Expected results:
When step 4 is done, it should be applied only for the letter ((U+0d38) + (0d4d)
+ (0d31) + (0d4d) + (0d31))

Rahul is our Indic font maintainer for this cycle. Reassigning to him first.

Look like this is a Qt problem. Reassigning to Qt.

There are two problems here.

1. character at step 4 isn't conjunct properly
   in gedit, [step 4's char][step 2's char][step 3's char] though,
   in kedit, [step 2's char][step 4's char][step 3's char]

2. the character width is miscalculated internally
   actually the cursor position is at the end of line afterward. but the
character width is miscalculated or ignored one character's width perhaps, then
it just looks like that.

 as per comment by Sachin as following:
This is the bug which is filed against three different problems, which includes
cursor position, pango issue, and vowel issue. So I filed 3 different bugs and
submitted patch for two QT related bugs.
As per order
1. Cursor position issue with QT in ml_IN
2. Voewl assignment issue with QT in ml_IN
3. Vowel assignment issue with pango in ml_IN
filing bug later...

my patch

I wrote a patch for fixing bug238896, bug223169 and bug223170.
And I modified indic_shape_engine( ) in this patch, let it handle one by one
syllable, not handle all syllables together.
It can fix the three bugs only by this way.

Comment 4 Bug Zapper 2008-04-04 00:28:28 UTC
Based on the date this bug was created, it appears to have been reported
against rawhide during the development of a Fedora release that is no
longer maintained. In order to refocus our efforts as a project we are
flagging all of the open bugs for releases which are no longer
maintained. If this bug remains in NEEDINFO thirty (30) days from now,
we will automatically close it.

If you can reproduce this bug in a maintained Fedora version (7, 8, or
rawhide), please change this bug to the respective version and change
the status to ASSIGNED. (If you're unable to change the bug's version
or status, add a comment to the bug and someone will change it for you.)

Thanks for your help, and we apologize again that we haven't handled
these issues to this point.

The process we're following is outlined here:

We will be following the process here:
http://fedoraproject.org/wiki/BugZappers/HouseKeeping to ensure this
doesn't happen again.

Changing version to '9' as part of upcoming Fedora 9 GA.
More information and reason for this action is here:

Comment 8 Bug Zapper 2009-06-09 22:34:44 UTC
This message is a reminder that Fedora 9 is nearing its end of life.
Approximately 30 (thirty) days from now Fedora will stop maintaining
and issuing updates for Fedora 9.  It is Fedora's policy to close all
bug reports from releases that are no longer maintained.  At that time
this bug will be closed as WONTFIX if it remains open with a Fedora 
'version' of '9'.

Package Maintainer: If you wish for this bug to remain open because you
plan to fix it in a currently maintained version, simply change the 'version' 
to a later Fedora version prior to Fedora 9's end of life.

Bug Reporter: Thank you for reporting this issue and we are sorry that 
we may not be able to fix it before Fedora 9 is end of life.  If you 
would still like to see this bug fixed and are able to reproduce it 
against a later version of Fedora please change the 'version' of this 
bug to the applicable version.  If you are unable to change the version, 
please add a comment here and someone will do it for you.

Although we aim to fix as many bugs as possible during every release's 
lifetime, sometimes those efforts are overtaken by events.  Often a 
more recent Fedora release includes newer upstream software that fixes 
bugs or makes them obsolete.

The process we are following is described here: 

Comment 9 A S Alam 2009-06-11 07:04:42 UTC
Re-Opening to following in Fedora 11

Comment 10 A S Alam 2009-06-11 07:05:05 UTC
following in Fedora 11
