[Bug 2230471] New: [Lenovo] GB 18030-2022 compliant Chinese font needed for OS preloads in China

https://bugzilla.redhat.com/show_bug.cgi?id=2230471

Bug ID: 2230471
           Summary: [Lenovo] GB 18030-2022 compliant Chinese font needed
                    for OS preloads in China
           Product: Fedora
           Version: 38
          Hardware: x86_64
                OS: Linux
            Status: NEW
         Component: Fonts
          Assignee: [e-mail]
          Reporter: [e-mail]
        QA Contact: [e-mail]
  Target Milestone: ---
    Classification: Fedora

Description of problem:
The Chinese government have made it a requirement that OS vendors support GB
18030-2022. To my understanding this means that the preloaded OS needs to have
a font that supports this spec and if we don't have that we won't be able to
ship the Fedora OS in China.

I believe Fedora has the google-noto-cjk-fonts package and it looks like they
are working on having compliance for this specification (based on
https://github.com/notofonts/noto-cjk/issues/252)

The font is not part of the default install so I wanted to open the
conversation as to whether it can be included in the default workstation
include please.

If there is another font that is compliant available that I've missed let me
know - this isn't a world I know well (despite, bizarrely, the very first job I
ever had was making it so vector fonts could be rasterised for display :))

Version-Release number of selected component (if applicable): N/A

How reproducible: 100%

Steps to Reproduce: N/A
1.
2.
3.

Actual results: no compliant Chinese font available

Expected results:Compliant Chinese font available

Additional info:Let me know if there is anything we can help with directly
here. Our team in China can help :)

My immediate comment is just that we do install Google Noto CJK fonts by
default,
but those fonts are not (cannot be) officially certified for GB18030 afaik.

Thanks Jens - I thought they weren't in by default as I had to do a dnf install
on my machine to get them. I'll check on a fresh install as this one has been
upgraded from older versions.

On the official certification - I thought the 252 issue meant they were working
on making them compliant. Once that is completed do you know if the updated
version will cover us - I was assuming it would :) I can go and do more digging
if needed.

Yes, that is a good find.

I think that Noto Serif v2.002 release (based on
https://github.com/notofonts/noto-cjk/issues/252) fixes this

Can we put this on the todo list for a Fedora update please - it will make the
next preload image we do compliant for China
Let me know if there is anything I can help with

Thanks!

I think the google-noto-sans-cjk-vf-fonts-2.004 already in F38 should over
GB18030-2022 Level 2 according to the issue you list.
So that should be sufficient really, but we should update the serif font
anyway.

I opened bug 2244390 for updating google-noto-serif-cjk-vf-fonts to 2.002

(Fixed typo: over -> cover)

Also from my basic check the coverage of Noto Sans 2.004 and Noto Serif 2.001
looks similar for basic GB18030-2022 (without addendum 1
- also not ratified yet from my understanding) - though I haven't compared them
glyph for glyph.

Thanks Jens.
If we're already at a level that should meet the requirements I'm happy to
close this and then I assume when we get to testing Fedora39 the team in China
can confirm if any problems? I wouldn't do a glyph for glyph comparison :)

Let me know if I'm missing anything

In fact Fedora 38 already has:

google-noto-sans-cjk-vf-fonts-2.004

So you could perhaps test this already today if you wish.

(and F38 google-noto-serif-cjk-vf-fonts >= 2.001 is also available to install)

Sounds good - I've asked the team in China to have a look. Many thanks for all
the help
