anyway, these are just my suggestions. It might be better you get a second opinion from other CJK developers/users.

Also, I forget to include GNU unifont. Last year, Paul Hardy incorporate WenQuanYi's Han glyphs (WenQuanYi Unibit) to this font; the latest version of GNU Unifont now covers the entire BMP (probably the only one so far)

Although I know most of you prefer vector fonts and disable bitmaps in fontconfig, but I think it does not hurt to add it as the system fallback, in case people want more glyphs and don't care about bitmaps.

There is also a 69-unifont.conf, probably the differences between these unifonts and cjk fonts are not that big.
