[Fontconfig] Changing the default pattern weight via config?

[Akira TAGOH]

Well, this will works if the best matched fonts against the query pattern
has the medium weight because the evaluation of the score for the weight
isn't that higher priority in fontconfig. otherwise you may need to write
more, particularly for family name maybe.

<match>
  <edit name="weight" mode="append" binding="strong">
    <const>medium</const>
  </edit>
</match>

Without the above:
$ fc-match -f "%{family} - weight: %{weight}\n" "Source Han Sans CN"
Source Han Sans CN,思源黑体 CN,Source Han Sans CN Regular,思源黑体 CN Regular -
weight: 80

With the above:
$ fc-match -f "%{family} - weight: %{weight}\n" "Source Han Sans CN"
Source Han Sans CN,思源黑体 CN,Source Han Sans CN Medium,思源黑体 CN Medium -
weight: 100

HTH,
