My screenshot showed that the actual output used proper typographical
quotes, but that may be down to the font used.

I think the conclusion here is that we shouldn't do anything. Adobe
created two encodings -- the "standard" one (which is ASCII with some
alterations), and the ISOLatin1Encoding (which is 8859-1 with some
alterations). But we can't really detect these simply: a2ps, for
instance, uses 8859-1 instead,
%%BeginResource: encoding ISO-8859-1Encoding
enscript does the same, but in a different way:
%%BeginResource: procset Enscript-Encoding-88591 1.6.5 90
None of the .ps files I can find on this laptop uses ISOLatin1Encoding
(or the "standard encoding"), as far as I can see.
So 1) these encodings went out of fashion decades ago and, 2) even if we
wanted to support them, Emacs can't auto-detect when they're used.
