--- Comment #25 from Michael J Gruber mjg@fedoraproject.org --- Yes, this is about looking up the font, or the fontconfig coming with some fonts.
I'm still wondering though how the others (mupdf, firefox etc.) look up the font to get a different answer. Do they go through fontconfig but filter the results differently?
