patch to fix rachana rakar reordereing
In the patch r3 xx is ര + ്- this is wrong order for the prebase ra. It should be ് + ര( xx r3) Tried reversing it in the patch, but that cause other sequences fail(eg: ഗ്ദ്ധ്രോ, ക്ത്രോ ). (In reply to comment #5) > In the patch r3 xx is ര + ്- this is wrong order for the prebase ra. It > should be > ് + ര( xx r3) > > Tried reversing it in the patch, but that cause other sequences fail(eg: > ഗ്ദ്ധ്രോ, ക്ത്രോ ). We have not changed sequence, just moved sequence it to appropriate feature tag. see the earlier reph in pstf feature, it was using same sequence is -> "r3 xx" Created attachment 639852 [details]
this fixes ഗ്ദ്ധ്രോ string as well
I am getting same rendering of ക്ത്രോ in pango and in harfbuzz-ng, so no need to fix it.
Hi Ani, I think upstream has done some improvement in this regards, can you just get status update from them? Then might be we can look at open issues. The current status is as follows: Meera: 2. അഥൎവ്വം (ൎdot reph is positioned correctly, but വ്വം is incorrect) - not fixed 15. ക്ത്ര - fixed 19. ഖ്ര - not fixed/cannot be fixed at font level for mlym spec 55. സ്പ്ലേ - not fixed, would need glyph modification Rachana: 1. അൎത്ഥം (dot reph not formed) - fixed, dot reph is added to Rachana, positioning not correct yet 2. അഥൎവ്വം ((dot reph not formed) - fixed, dot reph added, positioning not correct yet 15. ക്ത്ര - fixed 19. ഖ്ര - not fixed/cannot be fixed at font level for mlym spec 53. സ്പ്രി - fixed 54. സ്പ്രേ (Meera does it right) - fixed Thanks Rajeesh for update. When do you expect next upstream release? If its bit far, i think we should build smc-fonts in Fedora with patch. This bug appears to have been reported against 'rawhide' during the Fedora 19 development cycle. Changing version to '19'. (As we did not run this process for some time, it could affect also pre-Fedora 19 development cycle bugs. We are very sorry. It will help us with cleanup during Fedora 19 End Of Life. Thank you.) More information and reason for this action is here: https://fedoraproject.org/wiki/BugZappers/HouseKeeping/Fedora19 Hi Rajeesh, Any further improvement in this? Hi Praveen, As most of the issues are fixed except ഖ്ര (which cannot be fixed for mlym script), we could do a new release as is. At the same time, discussion related to സ്പ്ലേ is going on in harfbuzz mailing list. Will discuss and update. Latest status in Rachana: 1. അൎത്ഥം - fixed 2. അഥൎവ്വം - fixed 15. ക്ത്ര - fixed 19. ഖ്ര - not fixed/cannot be fixed at font level for mlym spec 53. സ്പ്രി - fixed 54. സ്പ്രേ - fixed 55. സ്പ്ലേ - not fixed, probably need a contextual lookup (not sure how to) Rajeesh, that is really nice. As harfbuzz is getting integrated at more and more places. (gnome, libreoffice..) i think soonish we need upstream release of this, so that users can get latest version and smc-meera will work seamless with Harfbuzz. I'm glad to announce that both Rachana and Meera are ported to new mlm2 spec and all these issues are fixed. Even in old spec, "55. സ്പ്ലേ" is fixed too. We're planning a new release soon, stay tuned! smc-fonts-5.0.1-7.fc19 has been submitted as an update for Fedora 19. https://admin.fedoraproject.org/updates/smc-fonts-5.0.1-7.fc19 smc-fonts-5.0.1-7.fc20 has been submitted as an update for Fedora 20. https://admin.fedoraproject.org/updates/smc-fonts-5.0.1-7.fc20 Package smc-fonts-5.0.1-7.fc20: * should fix your issue, * was pushed to the Fedora 20 testing repository, * should be available at your local mirror within two days.

If problems still persist, please make note of it in this bug report. Rajeesh, do we have this bug open in upstream? If not i would like to keep this bug open until next upstream release. Yes, see #comment1 by Ani. We'll use the upstream bug for further developments on this. Thanks Praveen. smc-fonts-5.0.1-7.fc19 has been pushed to the Fedora 19 stable repository.
