Since pango dropped support for non-opentype bitmap fonts <https://gitlab.gnome.org/GNOME/pango/issues/386>, and terminus-font is PCF, it should be converted to be able to continue using it in pango apps. <https://fedoraproject.org/wiki/BitmapFontConversion#Steps> has a guide on doing it for terminus, so i think an USE flag would be nice. Reproducible: Always

Sergei, thank you! (In reply to Sergei Trofimovich from comment #1) > And seems to work at least in Alacritty. It works, but there is a spacing issue at font size 12. Same issue was discussed at [*], but it is not clear yet, what caused that. This could be a bug in media-libs/harfbuzz or x11-apps/fonttosfnt. [*] https://bugzilla.redhat.com/show_bug.cgi?id=1753295

Yeah, wading through all the issues around cairo/pango/harfbuzz and bitmap font conversion my impression was that font conversion will not be 1-1 perfect. The perfect solution would be to provide OTF fonts directly by terminus upstream. I sent an email upstream to see if it's feasible or if possible document a canonical way to convert the fonts to OpenType.
