Comment 16 for bug 475240

Shi Zhu:

I want to clarify that the issue you report here does not conflict
with the solution to this bug.

At the very beginning, I was also afraid of the CJK Han-variant problems as
you did. Fortunately, what ahavatar is not about that. It is
about Hangul, which Zen Hei has the full coverage inherited
from Ubuntu's default Korean fonts. So, in that sense, it does not
conflict each other to make both Chinese Han characters and Hanguls
look good under en_US locale. The solution is simply like
what I outlined in my previous post. I also filed another bug
to fontconfig to mitigate the needs for setting antialias=false
when using embeddedbitmaps, see
https://bugs.freedesktop.org/show_bug.cgi?id=24960

<side-note>
As you and Arne pointed out, Han glyph shape variant (or Z-variant)
is more challenging issue. My suggested solution is to keep zh_CN
as the default shape variant (because of its huge coverage) for all
non-CJK locales, and use CJK specific fontconfig files to enable their
own respective settings under the corresponding locales. The
fontconfig-voodoo
tool is a Ubuntu implementations to link a set of files per locale.
I also proposed a solution which can make CJK files concurrently used,
you can find a lot more discussions at

http://bugs.freedesktop.org/show_bug.cgi?id=20911
and
https://bugzilla.redhat.com/show_bug.cgi?id=499902

I wish people who cares about this problem to give a serious
review and push the upstreams to adopt this scheme.
