After all, that's what your patch > attempts to do, albeit indirectly, right? The patch I proposed basically implements the suggestions Stefan made in=20 and . Stefan=20 was responding to Glenn=E2=80=99s original bug report, which suggests tha= t it is=20 not a good idea for a face definition to specify a font explicitly, due=20 to portability problems on systems lacking the font. See the attachment=20 to for an example of how verbatim=20 text in TeX mode was displayed as little black boxes because TeX mode=20 specifies an explicit font on a platform lacking it. I am by no means an expert on Emacs fonts or on font technology in=20 general. That being said, I would like to fix this blocking bug, and=20 Stefan=E2=80=99s suggestion was the only concrete one on the table. If th= e patch=20 is problematic, then is there a better way to fix this bug? More=20 specifically: is it the introduction of =E2=80=98fixed-pitch-serif=E2=80=99= that you=E2=80=99re=20 objecting to, or the addition of FreeMono and Nimbus Mono L as fonts to=20 look for, or is it something else? Is there some way we could make the=20 patch less kludgy, while still addressing Glenn=E2=80=99s and Stefan=E2=80= =99s concerns?
