Family information differs: fc-query <-> fc-list, fc-scan
I use Manjaro with fc-version 2.13.1. I detected a difference in the family information of the fc commands (attached file). The Qt framework (QFontDatabase, addApplicationFont) has the same family like fc-query. I used following commands:
> F='%{family}<<%{file}\n'
> fc-query --format=${F} DroidNaskh-Bold.ttf
Droid Arabic Naskh<<DroidNaskh-Bold.ttf
> fc-scan --format=${F} DroidNaskh-Bold.ttf
Droid Serif<<DroidNaskh-Bold.ttf
> fc-list --format=${F} | grep DroidNaskh-Bold.ttf
Droid Serif<</usr/share/fonts/droid/DroidNaskh-Bold.ttf
I suppose fc-scan and fc-list have the wrong informations. Gottfrie DroidNaskh-Bold.ttf
