But it's *really* just one font name with one weight. there's no 's' case in it.

I didn't make the 'noto-sans-sc-fonts' wrong...

why? because it's stripped from the language specific tarballs and
contains all CJK support?

the old name was 'noto-sans-mono-cjksc-fonts' (but I think it should
be 'noto-mono-cjksc-fonts')

but since I decided to use region specific variants, the 'cjksc' is no
longer a proper name
although it *correctly* reflects the fact that these monospace fonts
cover all CJK locales.

anyway this is open to discuss because they're not installed by default.

they'll be dragged in only if the end users install
'noto-sans-sc-fonts' themselves.

Ha, yes, noto-sans-sc-fonts contains all weights and
noto-sans-sc-fonts-mini contains
regular and bold weights. the later is a minimal alternative of the former.

the later and those two weights can be put into the DVD, leaving everything else
in the remote repository.

I stripped the packages just to make sure every locale has it's own
meta package.

There's no space for another mega package (or it can exist but not
exist in DVD so
that a default localized installation will not install all other fonts
for other languages)

BTW now I can be sure that if you install noto-sans-jp-fonts-mini, the
old noto-sans-cjk-fonts
will be uninstalled. But I didn't find a way to update
noto-sans-cjk-fonts and install noto-sans-jp-fonts-mini
automatically accordingly. I wonder can it be called 'smooth update'?

PS: I think I should also make the noto-sans-jp-fonts-mini conflicts
with noto-sans-jp-fonts
because they both have regular and bold weights. the later should
provide the former.

Sure.

I've been working on it here in my fork:
https://github.com/marguerite/fonts-config

1. I modified the 'serif' to use 'Noto Serif SC' instead of 'AR PL
UMing' by default

2. I left the 'Noto Sans CJK SC' there in 59-*.conf

But since we will not use Super OTC or Language Specific variants any more,
these font names will be non-existent actually.

So I prepend/append the 'Noto Sans SC' stuff in 32-google-noto-cjk.conf to fake
a font (although I don't know if my fontconfig grammar is correct, please help).

I didn't use 'alias' because in certain cases users may make those namespaces
available by installing those variant themselves.

The same policy should be applied to serif too.

3. I have a TODO in my fork, you can check that. it's the goal we need to do:

3.1 *colored* emoji support out of the box (50-emoji.conf and a cairo patch)

https://github.com/googlei18n/noto-emoji/issues/36

3.2 modern symbol font (what's the difference between emoji font and
symbol font? are they the same?)

Deepin project have a 'deepin-opensymbol-fonts' which is 6 fonts that
provide 'MT Extra' 'Webdings'
'Wingding' 'Wingding 2' and two other symbol fonts on M$.

So it's a 100% alternative. we don't need to rely on the ancient one
from LibreOffice

3.3 Adobe Source Hans vs. Google Noto CJK.

They're actually the same with minor difference. eg: the weight.
https://qdan.me/list/VLPe5sfsxkFWYMmX

And Source Hans has a 'HW( half weight )' weight available only in its
language specific variants.

So I think we should use fontconfig to provide Adobe Source Hans as we can.

And only package those missing weights.

But I didn't start working on this at all.

3.4 re-evaluate the choicesin 60-family-prefer.conf

For example, we still have Wenquanyi Zen Hei in the preference of
'sans-serif', and those 'Shanghai Song Uni' and 'AR PL'

What are they? are they still installed on openSUSE by default?

our system fontconfig is not a trash...we shouldn't put everything here.

we should just have a working one, no need to prefer so many ancient
things that few knows today.

I think we can have a start by cleaning CJK substitutes.


Because I will not be available from April. 28th to May 1st. (National
Holiday leave).

So please just step in the any of these topics and send pull requests
to openSUSE/fonts-config
when you're ready.
