Comment 4 for bug 625163

Appreciate the patch provided by Ray Wang, but I'd rather we can improve in other ways:
1 language-support-fonts-zh-hans is a meta-package, and normally, we don't do anything else than dependency with this package.
2 69-language-selector-$lang-$country provided by language-selector, which mean language-selector is already handling it, so we shouldn't confuse the whole configuration here.

These files go into /etc/fonts/conf.avail/ (debian/install) and should be
linked to /etc/fonts/conf.d/ .

They replace 52-language-selector .

29-language-selector-$lang(-$country)
        * rendering information
        * should be linked by default (debian/rules)
        * excpetion: -zh should NOT linked by default.
          This the is old configuration from zh_{CN|HK|SG|TW} and has been set
          already by the ttf-arphic-uming font. If users require these settings
          for other chinese fonts (which is not recommended, because they don't
          contain bitmaps), then they can link the file by hand.
30-cjk-aliases
        * should be linked by default
69-language-selector-$lang-$country
        * mutually exclusive
        * depending on which language environment is chosen, one of these gets
          linked to /etc/fonts/conf.d/ . When the language environment is
          changed, remove this link first, then link the desired
          -$lang-$country file.
99-language-selector-zh
        * artificial emboldening for chinese fonts
        * should be linked by default (debian/rules

For most end users, when they choose their own language during installation, fonts will be configured accordingly.
