PostScript's default encoding isn't ISO Latin 1, but a non-standard
encoding called, ironically, StandardEncoding.

Section 5.9 of the PostScript Language Reference Manual (3rd Edition),
available in PDF format from Adobe's site, gives this example for
creating a copy of a font with a different encoding vector:

	/Helvetica findfont
	dup length dict begin
	{1 index /FID ne
	{def}
	{pop pop}
	ifelse
	} forall
	/Encoding ISOLatin1Encoding def
	currentdict
	end
	/Helvetica-ISOLatin1 exch definefont pop

ps.map should probably be doing this itself; I'll look into it.
