--- Comment #2 from Hin-Tak Leung htl10@users.sourceforge.net --- It is often enough to be noticeable, for sure. Anyway, I already added a section to my own fontconfig and wish not to see it again. For various reasons I like to have all the fonts installed, but not necessarily used.
In .config/fontconfig/fonts.conf under the <selectfont></selectfont> section:
--- <rejectfont> <pattern> <patelt name="family"><string>04b03</string></patelt> </pattern> </rejectfont> ---
