Bug ID: 1016989 Summary: [ml_IN] non-standard sequence sequence for stacked chillu-N and RRA in Lohit Malayalam font should be removed Product: Fedora Version: rawhide Component: lohit-malayalam-fonts Assignee: psatpute@redhat.com Reporter: samjnaa@gmail.com QA Contact: extras-qa@fedoraproject.org CC: fonts-bugs@lists.fedoraproject.org, i18n-bugs@lists.fedoraproject.org, psatpute@redhat.com
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.
