I filed the following bug report with Fedora Rawhide yesterday: https://bugzilla.redhat.com/bugzilla/show_bug.cgi?id=172526 The problem is that fake bold and italic are turned on in the /etc/fonts/fonts.conf file - and can not be turned off (as far as I can tell) without modifying that file. Since that file is not suppose to modified, there basically is not a proper way to disable them if you don't want them. If they were moved to a /etc/fonts/conf.d/ file - then packagers could package them as config missing ok (at least with rpm) and system administrators could remove them without modifying the main file. Another (better?) possibility would be to install them without numbers and install a numbered symlink that could just be removed. Another possibility that would require code (if it doesn't exist already - I could not find it) would be a configuration directive that tells fontconfig not to embolden or italicize a particular font. Maybe create a dummy boolean pattern that is set to true, which fake embolding and fake italics can check - and then they can be set to false for fonts that should not be fake embolded or italicized.
