Comment 15 for bug 1227034

Thanks for the tip, Pellaeon Lin! To me it's useful indeed.

$ LANG=zh_CN.UTF-8 fc-match 'sans-serif'
ukai.ttc: "AR PL UKai CN" "Book"
$ LANG=zh_HK.UTF-8 fc-match 'sans-serif'
uming.ttc: "AR PL UMing CN" "Light"
$ LANG=zh_TW.UTF-8 fc-match 'sans-serif'
DroidSansFallbackFull.ttf: "Droid Sans Fallback" "Regular"

Not good.

I made a couple of changes to language-selector:

and uploaded to my PPA at https://launchpad.net/~gunnarhj/+archive/fonts

$ LANG=zh_CN.UTF-8 fc-match 'sans-serif'
DroidSansFallbackFull.ttf: "Droid Sans Fallback" "Regular"
$ LANG=zh_HK.UTF-8 fc-match 'sans-serif'
DroidSansFallbackFull.ttf: "Droid Sans Fallback" "Regular"
$ LANG=zh_TW.UTF-8 fc-match 'sans-serif'
DroidSansFallbackFull.ttf: "Droid Sans Fallback" "Regular"

Looks promising, doesn't it? :)

I'd like a few Chinese users to test the language-selector version in my PPA.

Then there are a few questions:

* Should this change make it to the archive, or are there drawbacks?
* Should we add 'binding="strong"' to all the
  69-language-selector-zh-*.conf files to be safe?
* Should we add 'binding="strong"' to serif and monospace as well?
