praviN-gedit-comparision-f23-f24.png

Left: Fedora 23, gedit-3.18.3-1.fc23.x86_64
Right: Fedora 24 Alpha, gedit-3.19.5-1.fc24.x86_64

The text file praviN.txt used is exactly the same in Fedora 23 and Fedora 24 Alpha, but the rendering result in gedit looks different.

It seems to be a font issue.

This screenshot shows the difference in rendering between

   pango-view --font="Lohit Marathi" praviN.txt

(on top, correct) and

   pango-view --font="Lohit Devanagari" praviN.txt

below, wrong.

Parag Nemade wrote that the build of lohit-marathi is the same in 
F23 and F24 and then I noticed that I didn’t have lohit-marathi installed
on my F23 system. If I install it, I get the same problem on F23 as well.

I can reproduce issue. Working on finding cause.

Sorry, just the oppsoite, Lohit Marathi renders wrong.

More test cases is http://utrrs-testing.rhcloud.com/language/mr/gsub showing wrong rendering in firefox.

Post anaconda installation of F24 Alpha in Marathi and later after successful gdm login:

- lohit-devanagari-fonts seems installed by default
- lohit-marathi-fonts is not installed by default, but is available and  installable via 'dnf'.

$ rpm -q lohit-devanagari-fonts lohit-marathi-fonts
lohit-devanagari-fonts-2.95.2-2.fc24.noarch
package lohit-marathi-fonts is not installed


$ sudo dnf repoquery -l lohit-devanagari-fonts | grep conf
/etc/fonts/conf.d/65-1-lohit-devanagari.conf
/usr/share/fontconfig/conf.avail/65-1-lohit-devanagari.conf
$ sudo dnf repoquery -l lohit-marathi-fonts | grep conf 
/etc/fonts/conf.d/65-0-lohit-marathi.conf
/usr/share/fontconfig/conf.avail/65-0-lohit-marathi.conf
$ fc-match 
Lohit-Devanagari.ttf: "Lohit Devanagari" "Regular"


From above, have following query:

As 65-0 has higher weight compared to 65-1, shouldn't 'lohit-marathi-fonts' be installed by default ?


Agreed, broken rendering with 'lohit-marathi-fonts' needs further investigation.

$ rpm -q lohit-marathi-fonts
lohit-marathi-fonts-2.94.0-5.fc24.noarch
$ rpm -ql lohit-marathi-fonts | grep ttf
/usr/share/fonts/lohit-marathi/Lohit-Marathi.ttf

Opening 'Lohit-Marathi.ttf' with 'fontforge' reveals no GSUB and GPOS lookups.

Perhaps, I could be missing something.

Else, looking forward ...

lohit-marathi-fonts-2.94.0-6.fc24 has been submitted as an update to Fedora 24. https://bodhi.fedoraproject.org/updates/FEDORA-2016-7c7c27be74

Good catch. There was error while applying feature file to Lohit-Marathi.sfd. I have resolved errors in .fea file now. So should work properly.
