Recently Adobe & Google released a open-source pan-CJK font, Source Han Sans from Adobe or Noto Sans CJK from Google.

This font family features 7 font weights: ExtraLight, Light, Normal, Regular, Meidum, Bold, Heavy and their os2 weight are: 100, 300, 350, 400, 500, 700, 900 respectively.

However, in fontconfig, os2 weight class 350 and 400 both maps to weight 80 and I think this makes fontconfig or pango confuse about how to choose the default font.

In particular in the GktFontChooser user can't choose one of these fonts. To fix this we probably also have to fix Pango.

This issue is also reported to the source-han-sans project: https://github.com/adobe-fonts/source-han-sans/issues/5
