This bug and bug223170 have 4 problems, this patch only can fix one problem, so
it need be modified.

I wrote a patch for fixing bug238896, bug223169 and bug223170.
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.
The patch is below:

The problem with all three combinations still exists.
Please have a look in the bug.
Pango version: pango-1.19.3-1.fc9

Problem still exists and necessary action is highly appreciated.
Slight change in the first combination mentioned in the problem
Correct combination is:
0D05 + 0D2A + 0D4D + 0D17 + 0D4D + 0D30 + 0d47 + 0D21 + 0D4D.
Hello again Caolan,
All is fixed in icu-3.8.1-4.fc9 except for combinations like
0D05 + 0D2A + 0D4D + 0D17 + 0D4D + 0D30 + 0d47 + 0D21 + 0D4D
ie, If a consonant with 0D4D is followed by the combination of (a consonant +
0D4D + 0D30), the glyph of combination of (a consonant + 0D4D + 0D30) appears wrong.
please find the screenshot attached.
Created attachment 293869 [details]
Scrreshot for the problematic combination
So this is test-case number 252 of
If so can we change the text of that test to be ...
A PA VIRAMA GA VIRAMA RA VOWEL SIGN EE DDA VIRAMA
A PA VIRAMA GA VIRAMA RRA VOWEL SIGN EE DDA VIRAMA
to match the unicode code points used.
I think I can hack in a special case for this sort of thing in >= icu-3.8.1-5,
but I really should make some time to figure out all this from scratch and
re-examine all the malayalam specific stuff and see why it has become so much
more complex than all the other indics, perhaps in conjunction with testing icu
with the microsoft malayalam font instead of/as well as the lohit one.
