Title:
  WenQuanYi Zen Hei is prioritised above Japanese fonts for Japanese
  language text

Bug description:
  Binary package hint: ttf-wqy-zenhei

  (I hope I've picked the right place to start with reporting this bug.
  I find fontconfig and CJK font selection issues in general quite
  confusing.)

  In Karmic, running firefox seems to pick a non-Japanese font for displaying Japanese web pages. (You can tell because the preferred character styles are somewhat different.) This used to work in Jaunty, but Karmic makes a worse font choice. 
  [Details: I have LANG=en_GB.UTF-8 but also PANGO_LANGUAGE=en;ja to tell Pango to guess Japanese if it has to guess. I'll attach the result of running a firefox with FC_DEBUG=1 and looking at a sample page with problems; you can see it asking for a font with 'lang: "ja"' and getting back "WenQuanYi Zen Hei", so I don't think firefox is at fault here.]

  This seems to be because if we ask fontconfig for a "Sans" font for
  Japanese text it gives back the ttf-wqy-zenhei one instead:

  $ fc-match Sans:lang=ja
  wqy-zenhei.ttc: "WenQuanYi Zen Hei" "中等"

  I do have Japanese fonts installed:

  $ fc-list :lang=ja
  WenQuanYi Zen Hei Mono,文泉驛等寬正黑,文泉驿等宽正黑:style=Medium,中等
  Sazanami Mincho,さざなみ明朝:style=Mincho-Regular,Regular
  WenQuanYi Zen Hei,文泉驛正黑,文泉驿正黑:style=Medium,中等
  VL PGothic,VL Pゴシック:style=regular
  Sazanami Gothic,さざなみゴシック:style=Gothic-Regular,Regular
  VL Gothic,VL ゴシック:style=regular

  (and if you don't ask for a Sans font you get back one of those:
  $ fc-match :lang=ja
  ttf-japanese-gothic.ttf: "VL Gothic" "regular"
  )

  I think that if the application is asking for a font to display
  Japanese text in, then all Japanese fonts should be prioritised above
  any of the other CJK fonts...
