Although we know we can customize via ~/.fonts.conf, it will be nice if
you provide alternatives for system wide
/etc/fonts/conf.avail/65-nonlatin.conf.
 * Chinese -> Japanese -> Korean (65-nonlatin-cjk.conf)
 * Japanese -> Korean -> Chinese (65-nonlatin-jkc.conf)
 * Korean -> Chinese -> Japanese (65-nonlatin-kcj.conf)
 * Japanese -> Chinese -> Korean (65-nonlatin-jck.conf)
 * Chinese -> Korean -> Japanese (65-nonlatin-ckj.conf)
 * Korean -> Japanese -> Chinese (65-nonlatin-kjc.conf)

Current 65-nonlatin.conf lists CJK fonts in somewhat random order.  This
is not so good. When multiple fonts are installed, the output becomes
different due to http://en.wikipedia.org/wiki/Han_unification problem.

One of the most annoing ones are "U+3001 IDEOGRAPHIC COMMA" and "U+3002
IDEOGRAPHIC FULL STOP" whose character positions differ among CJK
countries.

I think indics have similar problems.

As long as we have multiple choices as system default choice, we can
easily set up alternatives with update-alternatives(8).  Asking debconf
question to set this alternative is the next step.

Maybe at least we should provide something like Ubuntu has already done,
to improve the default user experience.

Ubuntu ships different fontconfig configurations for different choices
of languages using language-selector. We still don't have such thing,
and I believe language-selector's current implementation isn't ideal
enough to give user the ability to customize their configuration. But
I'd like to have some language based configuration examples left in
conf.avail to make people's life easier (so many people don't need to
write/share their own .fonts.conf anymore).

thanks

Actually #627939 and #498909 is talking about the same thing: CJK users
need special cares about their fonts configurations, and currently there
is no ideal solution to fit all the three languages. So we concluded
that we should provide some default configurations for different CJK
users, and let them to choose to enable which one in a user friendly way.

I'll try to see if I have the chance implement this by merging some
Ubuntu efforts.
