Screenshot for chillu conjuncts

Description of problem:
When chillu conjuncts are followed by any punctuation marks like "!", ".", ",", "'", "?" or SPACE, ie when a word ends with a chillu conjunct, and followed by a punctuation mark or a SPACE, using Backspace to delete the punctuation mark or SPACE results in the deletion of chillu conjunct together with the punctuation mark/SPACE.

Version-Release number of selected component (if applicable):
pango 1.26.0-1.fc12 i686

How reproducible:
Always

Steps to Reproduce:
1. Open gedit
2. type any of chillu conjunct, eg: 0D28, 0D4D, 200D
OR
type a word ending with chillu conjunct, eg: 0D05, 0D35, 0D28, 0D4D, 200D
3. type any punctuation marks like "!", ".", ",", "'", "?" or SPACE
4. Press Backspace
  
Actual results:
When using Backspace after chillu conjunct followed by punctuation mark or SPACE, instead of deleting punctuation mark or SPACE only, the chillu conjunct also gets deleted.

Expected results:
When using Backspace after chillu conjunct followed by punctuation mark or SPACE, only the punctuation mark/SPACE should get deleted.

Additional info:
1. This does not happen when chillu comes in between a word. eg:  നന്‍മ (0D28, 0D28, 0D4D, 200D, 0D2E)
2. This issue is not present in oowriter and kwrite. When above steps are reproduced, deletions happens in correct order. 
Versions used:
libicu-4.2.1-6.fc12 i686
qt-4.5.2-22.fc12 i686
3. Screenshot attached for chillu conjuncts and eg of words with chillu

Comment 3 Bug Zapper 2009-11-16 13:22:25 UTC
This bug appears to have been reported against 'rawhide' during the Fedora 12 development cycle.
Changing version to '12'.

Comment 5 Bug Zapper 2010-03-15 12:55:21 UTC
This bug appears to have been reported against 'rawhide' during the Fedora 13 development cycle.
Changing version to '13'.

Comment 6 Akira TAGOH 2011-05-24 12:39:35 UTC
Is this issue a known in upstream? otherwise please file a bug upstream. also good to test on f15 too if this issue still persists.

Comment 7 Pravin Satpute 2011-06-02 05:36:22 UTC
still present in pango-1.28.4-1.fc15.x86_64

Comment 8 Bug Zapper 2011-06-02 17:38:08 UTC
This message is a reminder that Fedora 13 is nearing its end of life.
Approximately 30 (thirty) days from now Fedora will stop maintaining
and issuing updates for Fedora 13.  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bug reports from releases that are no longer maintained.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 '13'.

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 13'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 13 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: 
http://fedoraproject.org/wiki/BugZappers/HouseKeeping

Comment 9 Akira TAGOH 2011-06-13 06:51:07 UTC
Hm, I guess this may be a duplicate of Bug#641290 in meaning of not checking the valid cluster for character break and the backspace behavior in pango.

that may be a good idea to post which combination is supposed to be valid for them.

Comment 10 Fedora Admin XMLRPC Client 2012-01-10 15:43:12 UTC
This package has changed ownership in the Fedora Package Database.  Reassigning to the new owner of this component.

same on f19 even.

So Ani, are you sure you filed this to upstream? otherwise please do that.

Comment 16 Pravin Satpute 2013-07-09 07:03:00 UTC
This is bit more generic bug.

Type any indic script character

"U+0915" + "200D" + "punct or space", it get clustered and complete sequence get deleted.

Comment 18 Akira TAGOH 2015-01-16 07:43:22 UTC
I guess the root cause might be similar to Bug#500110.

Comment 19 Pravin Satpute 2015-01-20 09:29:13 UTC
Yes, dependent vowel (characters with dotted circle) getting clubbed with preceding one.

Comment 20 Jan Kurik 2015-07-15 15:20:53 UTC
This bug appears to have been reported against 'rawhide' during the Fedora 23 development cycle.
Changing version to '23'.

(As we did not run this process for some time, it could affect also pre-Fedora 23 development
cycle bugs. We are very sorry. It will help us with cleanup during Fedora 23 End Of Life. Thank you.)
