Correct rendering of required combination.

From Comment #1,


The required combination is fixed in pango-1.25.5-1, qt-4.5.2-13 and libicu-4.2.1-6:

0D36 + 0D4D + 0D31  =>  ശ  +  ്  +  റ  = ശ്റ

Comment 3 sandeep shedmake 2009-09-15 05:08:11 UTC
From  Comment #2

Oops!!  I realized that smc-meera-fonts is the preferred font (as per the 90-smc-fonts.conf) over lohit-malayalam. 

Thereby, the required combination: 
0D36 + 0D4D + 0D31  =>  ശ  +  ്  +  റ  = ശ്റ      breaks in lohit-malayalam.

Comment 4 Ani Peter 2009-09-15 05:19:05 UTC
I confirm that this bug is filed for lohit-malayalam-fonts-2.3.8-1 as mentioned in the description. The combination works fine with all smc fonts.

Comment 7 Ani Peter 2009-09-18 06:15:59 UTC
Have tested Lohit-Malayalam. 
The combination is working perfect.

0D36 + 0D4D + 0D31  =>  ശ  +  ്  +  റ  = ശ്റ   

Thanks Sandeep.

Comment 8 Pravin Satpute 2009-09-21 12:16:36 UTC
build lohit-malayalam-fonts-2_4_4-1_fc12
will be available in wed. rawhide

Comment 9 sandeep shedmake 2009-09-23 06:30:57 UTC
From Comment #8,

Following combination:
0D36 + 0D4D + 0D31  =>  ശ  +  ്  +  റ  = ശ്റ 

can now be obtained from build lohit-malayalam-fonts-2_4_4-1_fc12 (available in Rawhide).

Thereby, closing this bug.
