[Pkg-fonts-devel] Bug#854772: fonts-noto-cjk: JP font was always (wrongly) selected under Chinese locale

[Boyuan Yang]

Package: fonts-noto-cjk
Version: 1:1.004+repack2-1
Severity: important
Tags: upstream

On any Debian system with fonts-noto-cjk installed with Chinese locale (e.g.,
zh_CN.UTF-8),
The JP font ("Noto Sans CJK JP" "Medium") always has a higher priority than
SC/TC font
("Noto Sans CJK SC" "Medium"), which is apparently a bug.

I believe this is an (upstream) bug in the font, not fontconfig. Someone said
that it is
because the JP font itself declared "zh" in "lang" attribute. But anyway we
should find
a way to fix it.

To reproduce it:

* Install a fresh Debian Stretch system, enable zh_CN.UTF-8 locale.
* Install fonts-noto-cjk.
* "fc-match -a sans" will match JP font.
