Include more fonts (google-noto-fonts-all) by default

[myyc]

it seems like there is general agreement that noto fonts are a good fallback for all sorts of languages and many of them are installed by default, but the selection seems a bit arbitrary (e.g. why is cherokee in while mongolian or javanese are out). would it make sense to have google-noto-fonts-all installed by default?

I don't really know why some fonts are included and not others.

I tend to agree we should increase our default coverage: maybe you could open a langpacks bug to request having Mongolian and Javanese fonts pre-installed. I think it's better to discuss specific cases than just say "let's install everything by default".

Also this applies equally to Fedora Workstation et al, so it's not Silverblue specific.

Yes, that sounds good to me.
Installing everything by default may be not that useful I'd say. google-noto-fonts has >300 sub packages at the moment though, about 50% of them can't be chosen automatically unless one type a character through an unicode codepoint or a font directly.

We should clarify our support criteria.

the only reason why i suggested all the noto fonts is that the exclusion of some seems purely discretionary. the purpose of noto (allegedly) is a blanket coverage within a single font family. yes, it installs a lot of packages but maybe the issue is fedora's? arch, for instance, only has four noto packages (main, cjk, extra, emoji).

either way, thanks for the discussion, regardless of whatever decision you want to take :)

If the size is reasonable, we should consider installing them all. That way we won't have to wonder why something is missing again. I don't know how much this amounts to.

There are also a few concerns on installing google-noto-fonts-all.

• google-noto-fonts-all contains duplicate fonts with a static (non-variable) and a variable font. Variable fonts are supposed to be used by default. However, static fonts will be picked up when both are installed at the same time because of the backward compatibility for some applications. So installing them all together isn't desired for us.
• We have google-noto-fonts-all-static and google-noto-fonts-vf. However, all the variants isn't necessarily provided on both static and variable fonts. something is only available for static and vice versa. They aren't superset nor subset.
• 426MiB will be required to install google-noto-fonts-all (+414MiB more than currently installed by default) just FYI
