I think this bug is the same as bug447035.
So we can close it.
:)

Screenshot with correct rendering after testing in gedit

Tested all three combinations mentioned in this bug on latest pango: 
pango-1.26.0-1.fc12.i686
Result as follows:

[അപ്ഗ്റേഡ്]
0D05 + 0D2A + 0D4D + 0D17 + 0D4D + 0D31 + 0d47 + 0D21 + 0D4D
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 : 0D05 + 0D2A + 0D4D + 0D17 + 0D4D + 0D30 + 0d47
+ 0D21 + 0D4D  (അപ്ഗ്രേഡ്) ­.
This works perfectly now

 [വ്യക്തം]
0D35 + 0D4D + 0D2F + 0D15 + 0D4D + 0D24 + 0d02
This works perfect now.


5) [ഇന്‍സ്റ്റോള്‍]
0D07 + 0D28 + 0D4D + 200D + 0D38 + 0D4D + 0D31 + 0D4D + 0D31 + 0D4B + 0D33
+0D4D + 200D
This works perfect now.

Screenshot attached.
