Description Amitakhya Phukan 2008-03-14 03:29:37 EDT
Description of problem:
I find that consonant for character "ra" Unicode U+09F0 breaks in latest rawhide.

Version-Release number of selected component (if applicable):
qt4 : qt4-4.3.4-5.fc9

How reproducible:

Steps to Reproduce:
1. Open kate or kwrite or kaider and try to write combinations like U+0995
U+09CD U+09F0.
2. You can see the characters don't combine, it breaks.
Actual results:
The consonant combinations break

Expected results:
The consonant combinations should not break.

Additional info:
I have tested the double and triple combinations of U+09F0 only. More test
updates I will put here. Bengali and assamese use the same font file,
lohit-bengali. Whereas bengali combinations don't break, assamese combinations
break. Also, the combinations don't break in GNOME applications.

the characters given in the attachments can be typed in assamese phonetic
keyboard as follows :

1. n/f/r
2. k/r
3. r/k

aalam, hopefully this will help you.
Comment 4 Kevin Kofler 2008-03-14 06:34:06 EDT
Do you know what version it last worked with? Is this something which was 
always broken in Qt 4 or a recent regression?
Comment 5 Amitakhya Phukan 2008-03-14 06:39:36 EDT
kevin, i just tested it today and hence i don't know about previous versions of
qt 4. also, i mostly work with stable releases and hence this problem was
unknown to me even if it existed in previous fedora rawhide.
Comment 6 Amitakhya Phukan 2008-03-14 06:40:31 EDT
aalam, the characters that are going to be displayed are as follows :

1. n/f/r : ন্ত্ৰ
2. k/r : ক্ৰ
3. r/k : ৰ্ক

Thanks Amit, it is help a lot
Comment 8 Rex Dieter 2008-03-14 10:41:54 EDT
If this is something that requires upstream attention (and fixes), a better
approach would be to report this to trolltech:

Pravin, thanks for the patch. I already sent the patch to qt-bugs so that it's 
included in next release version.
Comment 13 Amitakhya Phukan 2008-03-28 02:14:33 EDT
I tested the patch with Pravin in his demo program.

1. U+0995 U+09Cd U+09F0 works fine

I noticed,

1. U+09F0 U+09CD U+0995  breaks.

I hope the fix will come soon.
