            Bug ID: 1016989
           Summary: [ml_IN] non-standard sequence sequence for stacked
                    chillu-N and RRA in Lohit Malayalam font should be
                    removed

This is related to bug #1016984 which I reported just now.

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. In bug #1016984 I have requested to add it.

Apart from that, note that currently the sequence being used to display stacked
chillu-N on top of RRA in Lohit font is ന്റ = 0d28 0d4d 0d31. This is
non-standard. It is inadvisable to retain this sequence as having two
canonically non-equivalent sequences display the same is a security issue of
confusability.

My request from the POV of being standard-compliant would be to remove this
sequence.

However I am sure (based on personal email communication) there will be
objection from people such as Santosh Thottingal since they do not agree with
the standard on this matter. They maintain that NA + VIRAMA + RRA is the
correct sequence to get this display.

I have told them that if they disagree with the standard then they should
discuss the matter on the Unicode and try to make the Unicode Technical
Committee accept their view. Otherwise such sequences will just be
standards-non-compliant and the existing diversified situation will only be
aggravated.

Certainly the current standard-prescribed sequence should be included to be
standards compliant. For that I have already filed the separate bug. For 100%
compliance the old non-standard should be removed. To track that I am filing
this bug now.

In the face of community objection, it is up to the project maintainer to
decide about this.

--- Comment #1 from Pravin Satpute <psatpute(a)redhat.com&gt; ---
This bug report is very clear and i agree with you. but surprisingly some fonts
around does not follow it.

Dunno why people are considering U+0D28 and U+0D7B as equivalent.

In reality 

u0D28 + u0D4D + u200D = u0D7B

I hope people around are not using this u0D28 instead of u0D7b and already
created some data.

1. There is already good amount of data available using this legacy sequence. 
2. Same time, this sequence is supported in Lohit from long time. Removing it
will introduce regression.

Lohit2 will also support this sequence with standard one given in Unicode.
Closing this as a Not a Bug. Feel free to reopen if more issues.

Dear Pravin,

Based on the way you have handled bug 1078661 don't you think in the case of
Malayalam also you can have users use the old version of the font if they want
the old behaviour and the new version of the font should support only the
standards-compliant sequence?

Since Lohit is a high visibility font especially used in Linux/Android devices
and all, if we are standards compliant then it will encourage others to be so
as well in their input methods etc. if we are non-compliant then we are merely
encouraging people to continue using non-standard input sequences.

I strongly doubt that in latest Windows 8 fonts the old sequence would be
supported (but I don't have that OS so I can't test).

Malayalam is bit complicated when comes to Unicode standards. We have seen
issues with community and Unicode.

Just tested with Google noto fonts and even they are supporting this sequence.
Reason should be same backward compatibility.
