--- Comment #18 from Akira TAGOH tagoh@redhat.com --- just FYI, aside from XSETTINGS issue, abattiscantarell-fonts has a trick in 31-cantarell.conf to fallback to other fonts due to the glyph coverage in Cantarell font maybe with replacing the family name as the weak binding. for this reason, it may depends on the language how it works:
$ LANG=en_US.UTF-8 fc-match Cantarell Cantarell-Regular.otf: "Cantarell" "Regular" $ LANG=ja_JP.UTF-8 fc-match Cantarell VL-PGothic-Regular.ttf: "VL Pゴシック" "regular"
