Dave,
I have an answer from Ghostscript/Artifex. It points to footnote in
PRML, the PostScript Language Reference
Manual (see p785 of the 3rd edition):
3. The ISOLatin1Encoding encoding vector deviates from the ISO 8859-1
standard in one
respect: the character at position 140 is quoteleft, whereas the
ISO standard specifies
grave. A PostScript program needing to conform exactly to the ISO
standard should
create a modified encoding vector with this entry changed.
So what is displayed in the buffer as
character: ` (96, #o140, #x60)
is in reality, printed on some medium or on screen
character: ‘ (8216, #o20030, #x2018)
or: instead of /grave the character /quoteleft is encoded here.
You can try yourself to open the PS file (any with a `) without any
precautions and it will be Unicode or ISO Latin, maybe some ASCII. In
a second buffer open the same file–actually a copy, because I don't
think that GNU Emacs can display the same file in two different
encodings–in adobe-standard-encoding. To do so start with:
C-x RET c adobe-standard-encoding RET v
I assume you are in dired-mode and the text cursor is on the copy.
Otherwise you have to use C-x f. Now notice the difference!
I think of continuing the conversation with the Ghostscript folks
(extending to PDF), and I also sent a bug report to the GNU Emacs
developers because PS files are *not* opened in a PostScript but some
text encoding. With the consequence that folks like you and me think a
` is a ` while it's a ‘...

Greetings
