Description Ani Peter 2008-01-31 09:01:04 UTC

+++ This bug was initially created as a clone of Bug #402331 +++

Description of problem:

In lohit-malayalam font,  0D28 + 0D4D + 200D + 0D31 (key 'V', key 'D', key ']'
and  key ' shift J'  on  malayalam inscript keyboard)  gives the conjunct  ' 
ന്‍റ ' . But  the correct combination is  0D28 + 0D4D + 0D31   (type key 'V', key
'D'  and  key ' shift J'  on  malayalam inscript keyboard) which must give the
conjunct  ന്‍റ.

Version-Release number of selected component (if applicable):

How reproducible:

Always

Steps to Reproduce:

1.Open gedit/kedit.
2.Type unicode 0D28, 0D4D, 200D , 0D31(or  type  key 'V', key 'D', key ']' and 
key ' shift J'  respectively using Malayalam Inscript).
3.Result   is    ന്‍റ.
  
Actual results:

key ' shift J'  respectively using Malayalam Inscript).
3.Result   is    ന്‍റ.

Expected results:

1.Open gedit/kedit.
2.Type unicodes  0D28 + 0D4D + 0D31  (or type key 'V', key 'D'  and  key ' shift
J'   respectively using Malayalam Inscript).

Appreciate if you could let me know the status of this bug as this has to be
fixed immediately before next release.

This is a very basic but very critical bug and hence must be fixed urgently.

Thanks
Ani

Rahul, we had a personal discussion on this bug last week. Is the issue clear
for you or do you still have any doubts?

Thanks
Ani

Ani, thanks for the concern. The problem is absolutely clear to me. It also has
a relation the  other bug about chillaksharam right now.

Ani, can you please test this font file before I build it for fedora?

Rahul ,

I still find this is not fixed completely. Now the result is just the key
sequence when 0D28 + 0D4D +  0D31 is used.

Problem : 0D28 + 0D4D + 200D + 0D31 has to be used for getting the conjunct.

Expected result: 0D28 + 0D4D +  0D31 must give the desired conjunct.

Please have a look on the screenshot attached on Comment #5 

Let me know if any more queries.

Thanks
Ani

Please ignore the comment #12 as its a repetition of comment #10. Instead please
have a look in the follwing:

Rahul,

One more thing I would like to mention is that, now as the chillu is not working
anywhere, currently 0D28 + 0D4D + 200D + 0D31 is also not giving the conjunct. I
have already showed you the glyph of the conjunct in the font file. have
attached the same as in comment #11

Thanks
Ani

-- Additional comment from rbhalera on 2008-01-23 08:08 EST --
Ani, from the screenshot in comment #5 attached by you, I assume you do not want
the conjunct to be formed for 0D28 + 0D4D + 200D + 0D31?

Fixed in lohit-fonts-malayalam-2.1.8-1.fc9.

Comment 1 Ani Peter 2008-01-31 09:20:47 UTC

Hi Caolon,

This is a special case where 0D28 + 0D4D + 0D31 gives a special glpyh. Have
included this in test case too. Will provide you the test case number once its
available on batsman. screenshot attached.

Currently, this is fixed in pango, fonts-malayalam and working perfect with gedit.

Thanks
Ani

Comment 3 Rahul Bhalerao 2008-01-31 10:03:30 UTC

Caolon,

I believe this is not an ICU bug. The bug was fixed in font (#402331) and no
modifications in pango were required to make it work on pango. So I guess there
should not be any modifications in ICU as well. If at all the same font is not
working on ICU, I think its because of the special issue of 0x0D31, which is
fixed in pango and filed for ICU on #424661.
Thanks.

Comment 5 Caolan McNamara 2008-01-31 15:32:51 UTC

Reverted the hack that we had in place in icu to get the original results for
the rest of the something + 0d4d + 0d31 ones that have now been changed. So
should be good in icu-3.8.1-4.fc9. 

The same hack for the something + 0d4d + 0d30 test-cases to get the right
results remains, which does sort of me dubious about the hack in icu as pango
remains "broken" on those test-cases.

Comment 6 Ani Peter 2008-02-04 06:09:40 UTC

Hi Caolon,

Working perfect in icu-3.8.1-4.fc9. Tested and confirmed.

Thanks
Ani
