[Fedora-i18n-bugs] [Bug 1016984] New: [ml_IN] Unicode standard sequence for stacked chillu-N and RRA not supported in Lohit Malayalam
1 a.m.

Bug ID: 1016984
Summary: [ml_IN] Unicode standard sequence for stacked chillu-N
and RRA not supported in Lohit Malayalam
Product: Fedora
Version: rawhide
Component: lohit-malayalam-fonts
Assignee: psatpute(a)redhat.com
Reporter: samjnaa(a)gmail.com
QA Contact: extras-qa(a)fedoraproject.org
CC: fonts-bugs(a)lists.fedoraproject.org,
i18n-bugs(a)lists.fedoraproject.org, psatpute(a)redhat.com
Description of problem:
As per TUS 6.2 chapter 9.9 p 321 (p 351 of PDF) the correct sequence to get the
display of stacked chillu-N on top of RRA in Malayalam is: CHILLU N + VIRAMA +
RRA. That is: ൻ്റ = 0d7b 0d4d 0d31. However, currently Lohit Malayalam font
does not support this sequence.
Testing Lohit Malayalam and Google Noto Sans Malayalam with latest HarfBuzz git
head shows that Lohit is not capable of rendering this sequence correctly
whereas Noto is capable.
Please fix it so that ൻ്റ = 0d7b 0d4d 0d31 is correctly rendered as stacked
chillu-N on top of RRA.
Version-Release number of selected component (if applicable):
2.5.4

--- Comment #1 from Pravin Satpute <psatpute(a)redhat.com> ---
Ok, after some more work on it i understood it is classic "NTA" dual encoding
issue. Introduced due to addition of atomic chillu.
Here i am in favor of providing backward compatibility and avoid dual encoding.
So we will keep with giving only one rule for NTA. i.e.
u0D28 + u0D4D + u0D31 = NTA
and will avoid having this one.
do you aware any normalization from Unicode on this front?

Hello Pravin. I would advise going by the standard. It was unavoidable that the
chillu encoding would break some things and this was one of them.
But if Lohit also continues to cater to the old system, then people will still
continue to use it and not move to the current system at all, especially if you
do not provide the current standard. "Backward compatibility" does *not* mean
not moving forward at all! And always in software backward compatibility can
only be provided to a certain extent, not permanently.
The standard tells you to do 0D7B CHILLU_N + 0D4D VIRAMA + 0D31 RRA to get
stacked chillu-N with RRA below. If one does not follow the standard, then what
is the point in the standard?
If I am not convincing you, please ask on the indic@unicode list.

Yes, discussing on indic@unicode is more important.

u0D28 + u0D4D + u0D31 = NTA
and will avoid having this one.
Pravin can you please clarify what you have done on this? In
https://bugzilla.redhat.com/show_bug.cgi?id=1016989#c2 you say you will give
both rules i.e. with NA and also chillu N but above you say you will give only
old rule with NA.
