The only existing variable which controls font display through matching
fonts against a regexp has been effectively abandoned over the years,
and is nonfunctional on all systems besides X and Android.
(Grep for Vvertical_centering_font_regexp: only sfntfont.c and xfont.c
consult it.)

A compelling reason for us _not_ to introduce more such variables, as
they will soon fall into disuse and neglect.

Yes, and don't these packages require using their own specialized icon
fonts to begin with?
