Comment 2 LingNing Zhang 2007-06-13 08:09:24 UTC 
I wrote a patch for fixing bug447033, bug447034 and bug447035.
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.

This patch is below:

Tested in pango-1.26.0-1.fc12.i686. Confirmation about the bug  for details mentioned in the description as follows:

1st combination:0D21 + 0D4D + 0D31 + 0D48 + 0D35 + 0D4D  (ഡ്റൈവ്)
There was a confusion between usage of 0d30 and 0d31 earlier. Finally after lots of discussion in the community, decided to use 0d30 for such combinations. Hence the combination will be : 0D21 + 0D4D + 0D30 + 0D48 + 0D35 + 0D4D  (ഡ്രൈവ്) ­this works perfectly now.

2nd combination: 0D05 + 0D2A + 0D4D + 0D21 + 0D47 + 0D31 + 0D4D + 0D31 + 0D4D (അപ്ഡേറ്റ്)
This also works perfectly.
