Thank you for the prompt reply.  But, with that in
~/.fonts.conf, "WenQuanYi Zen Hei" is still listed by the
command "fc-list :lang=ja".

I'm not sure that is a good solution.  As we already have
better Japanese fonts than "WenQuanYi Zen Hei", I think just
telling fontconfig that the font doesn't support "ja" is the
simplest and best solution.  Isn't it possible?
