1074022 - switch to using Source Han Sans as the default sans serif font for CJK languages

Status: RESOLVED WONTFIX

(Firefox OS Graveyard :: General, defect)

Description

[John Daggett (:jtd)]

Google and Adobe, together with a bunch of specialist type companies in various CJK countries, have developed a new open-source CJK font, Source Han Sans. Google is planning to release this as Noto Sans. At some point I think this will be the ideal CJK font for use with Firefox OS, as it supports a wider set of weights and has a richer set of font features available.

At this point I think this still needs to be evaluated more and there are probably font bugs that need to get worked out still but I definitely think we should track this effort and make use of it whenever it seems like the right point.

- The latest version of Noto Font for JP is 1.0.1.
- AOSP of Android L preview doesn't replace with Noto Font yet.

There are only Simplified Chinese glyphs were used in Droid Sans Fallback, making rendered texts in Traditional Chinese or other Hanzi/Kanji-used locales not following their locale usage[1]. 

The latest 1.0.1 release fixed most apparent problems we noticed for zh-TW so far (except HK glyphs [2]), for zh-TW we should be able to make this change.


[1] See https://github.com/adobe-fonts/source-han-sans/raw/release/SourceHanSansReadMe.pdf for story.

[2] Taiwan and Hong Kong has differences in glyphs, but since we only have zh-TW locale in Gaia, it should be safe to ignore this for now. 
The issue is also tracked in the project: https://github.com/adobe-fonts/source-han-sans/issues/48
