At least that, yes.  For PostScript and PDF output, font metrics
for the Times New Roman ASCII font are currently hardcoded in
term_ps.c, the number of supported glyphs is limited to 96 glyphs
per font style, and no other font can be used.  Generalizing font
support would be a major undertaking.

That statement is accurate.  Groff is to be recommended for that
purpose because it has better mdoc(7) support than other troff
implementations (except mandoc, of course).

Yours,
