Bug ID: 1809989
Summary: By default install Noto fonts for Unicode scripts not
already covered by default
QA Contact: extras-qa(a)fedoraproject.org
Target Milestone: ---
There is currently movement towards protecting browser users from font
fingerprinting. This means refusing, by default, to load user-installed fonts,
which makes the set of fonts that each OS installs by default even more
important than before.
W3C CSS WG issue:
Currently, Windows 10, macOS, Android, and Chrome OS provide broader
installed-by-default Unicode coverage than Fedora.
Examples of living scripts that have enough active users to make it to the list
but are not supported by default in Fedora 31 include Javanese, Sundanese,
Batak, Balinese, Mongolian, and New Tai Lue.
Egyptian hieroglyphs is an example of a dead script the Fedora 31 doesn't
support out of the box but Windows 10, macOS, Chrome OS, and Android do.
To remedy this with minimal disk space impact, I suggest the same approach that
Apple took. Apple bundles with macOS those Noto fonts that cover scripts that
were not already covered by the previous installed-by-default set of fonts on
macOS. In the macOS case, the on-disk footprint of the Noto fonts that were
required to take macOS to Android/Chrome OS-competitive Unicode coverage was
only a couple of megabytes. (The fonts are hidden in /Library/Application
Support/Apple/Fonts/Language Support/.) In the case of Fedora, the set of Noto
fonts required to reach the Chrome OS / Android level of script coverage is a
bit larger than in the macOS case but should still be manageable.
Please install, by default, those Noto fonts that provide support for scripts
that are not properly supported by the fonts that Fedora already installs by
