  Fontconfig lacks support for many OpenType/TrueType OS/2 font weight
  values. This causes a bunch of problems, like mixing up Demilight
  (weight=350) and Regular (weight=400).
  
  Although it's possible to write (dirty?) hacks for deb-packed fonts,

2016-04-02 Thread Gunnar Hjalmarsson 
Thanks for your attempt to fix it. Haven't tried the new patch yet, but
before I saw it, I created a new PPA for trying the Arch Linux way: A
possible upgrade to fc 2.11.94:

https://launchpad.net/~gunnarhj/+archive/ubuntu/fontconfig-test2

Much better result. :) (The below is without the influence of the
language-selector .conf files.)

$ fc-match -V
fontconfig version 2.11.1
$ fc-match -a | grep 'Noto Sans CJK SC'
NotoSansCJK.ttc: "Noto Sans CJK SC" "DemiLight"
NotoSansCJK.ttc: "Noto Sans CJK SC" "Regular"
NotoSansCJK.ttc: "Noto Sans CJK SC" "Medium"
NotoSansCJK.ttc: "Noto Sans CJK SC" "Thin"
NotoSansCJK.ttc: "Noto Sans CJK SC" "Light"
NotoSansCJK.ttc: "Noto Sans CJK SC" "Bold"
NotoSansCJK.ttc: "Noto Sans CJK SC" "Black"
$ fc-match -V
fontconfig version 2.11.94
$ fc-match -a | grep 'Noto Sans CJK SC'
NotoSansCJK.ttc: "Noto Sans CJK SC" "Regular"
NotoSansCJK.ttc: "Noto Sans CJK SC" "Medium"
NotoSansCJK.ttc: "Noto Sans CJK SC" "DemiLight"
NotoSansCJK.ttc: "Noto Sans CJK SC" "Light"
NotoSansCJK.ttc: "Noto Sans CJK SC" "Thin"
NotoSansCJK.ttc: "Noto Sans CJK SC" "Bold"
NotoSansCJK.ttc: "Noto Sans CJK SC" "Black"

I can't tell if it would be possible to have this accepted for 16.04. It
would be very interesting to know if fc 2.11.94 also fixes the Firefox
issue, which has been reported at bug #1468027 (see my latest comment
there).

Hi Mingye,

I tried to build fontconfig in a PPA with your patch. The patch applies,
but unfortunately the build failed.

"error: could not locate FcRangeCreateDouble in src/*.c"

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:

Note that this fix introduced bug 82228 as lerp doesn't handle dy == 0.

Hi again, Mingye!

I think that fontconfig .conf files are effective whether the fonts were
installed via .deb packages or in some other way, as long as the font
files are placed in a directory which fontconfig looks at. With that
said, if it's possible to make fontconfig pick the most sensible default
font weight without extra configuration, it's indeed a better way.
