https://en.wikipedia.org/wiki/Tifinagh (Moroccan) - most important (missed from bug 2318769)

I think this would only leave: Church Slavonic as tofu on wikipedia more or less
(which doesn't seem covered by Noto):

Comment 1 Jens Petersen 2025-05-15 10:19:02 UTC

I would suggest to move google-noto-sans-tifinagh-fonts from '-kab' to default-fonts-ber (Berber).

Comment 2 Akira TAGOH 2025-05-16 06:41:49 UTC

fontconfig doesn't support zgh, tdd, and syl

Comment 3 Akira TAGOH 2025-05-16 06:45:12 UTC

fontconfig has ber_dz and ber_ma though, ber_dz is the same to kab but ber_ma isn't. So simply default-fonts-ber may be not sufficient.

Comment 4 Akira TAGOH 2025-05-20 02:49:10 UTC

For reference, posting same comment here from https://bugzilla.redhat.com/show_bug.cgi?id=2318769#c18

fontconfig has both ber-dz and ber-ma as well as kab though, ber-dz is same to kab but ber-ma has different coverage.
Taking a look back on the introduction of default-fonts-kab, that was maybe wrong because Noto Sans Tifinagh* has ber-ma coverage only:

$ for i in /usr/share/fonts/google-noto/NotoSansTifinagh*; do fc-query -f "%{file}:%{lang}\n" $i; done
/usr/share/fonts/google-noto/NotoSansTifinagh-Regular.ttf:ber-ma
/usr/share/fonts/google-noto/NotoSansTifinaghAPT-Regular.ttf:ber-ma
/usr/share/fonts/google-noto/NotoSansTifinaghAdrar-Regular.ttf:ber-ma
/usr/share/fonts/google-noto/NotoSansTifinaghAgrawImazighen-Regular.ttf:ber-ma
/usr/share/fonts/google-noto/NotoSansTifinaghAhaggar-Regular.ttf:ber-ma
/usr/share/fonts/google-noto/NotoSansTifinaghAir-Regular.ttf:ber-ma
/usr/share/fonts/google-noto/NotoSansTifinaghAzawagh-Regular.ttf:ber-ma
/usr/share/fonts/google-noto/NotoSansTifinaghGhat-Regular.ttf:ber-ma
/usr/share/fonts/google-noto/NotoSansTifinaghHawad-Regular.ttf:ber-ma
/usr/share/fonts/google-noto/NotoSansTifinaghRhissaIxa-Regular.ttf:ber-ma
/usr/share/fonts/google-noto/NotoSansTifinaghSIL-Regular.ttf:ber-ma
/usr/share/fonts/google-noto/NotoSansTifinaghTawellemmet-Regular.ttf:ber-ma

Then we should rename default-fonts-kab to default-fonts-ber_MA and need to find out a font which has ber-dz or kab coverage if we want to provide a font for them.

Comment 5 Jens Petersen 2025-05-20 04:01:41 UTC

Okay sorry, sounds like renaming -kab is perhaps not such a good idea then.

May still be good to consider installing the font by default.
Though I think Latin is preferred modern script iiuc.

Wonder if there is any better reference page/site than Wikipedia..

Comment 6 Akira TAGOH 2025-05-20 04:36:48 UTC

We would rather rename -kab to -ber_MA as I mentioned the above. NotoSansTifinagh*.ttf is what we currenctly have in default-fonts-kab and they don't have kab coverage as noted.
