Looks good, but...

... I'm not sure whether that IBM document the Wikipedia page has
sourced the table for is authoritative.  There seems to be many versions
of the Adobe PostScript ISO-8859-1-alike code page.

Hm...  I don't think that's what we need here -- we need the encoding of
text files, not fonts.

That's the one we have in Emacs today as adobe-standard-encoding, but it
seems very odd.  I mean, both stdenc.txt itself, as well as our
interpretation of it, because stdenc.map leaves most 8-bit chars
undefined.

So I'm not sure what we should do here, if anything.  Is there some
Adobe printing expert we could reach out to?  :-)
