Subject: bug#7786: 23.2; Encoding of PostScript files
Date: Wed, 5 Jan 2011 01:18:19 +0100 [thread overview]
Message-ID: <F265AF4E-C402-4C84-9B50-9D8061FE896B@Freenet.DE> (raw)
Hello!
When I open a PostScript file it's opened "(encoded by coding system
undecided-unix)" – as the *Help* buffer explains after invocation of C-
u x =.
This is incorrect, because, as PRML, The PostScript® Language
Reference manual, explains in a footnote near the end, on encodings:
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.
IMO GNU Emacs should open a PostScript file in adobe-standard-
encoding, except it sees in the file that the font(s) used is (are) re-
encoded in ISOLatin1Encoding (which is *not* the same as ISO 8819-1),
CE Encoding, or whatever.

Üblicherweise begehen Menschen beim Entwerfen vollkommen
narrensicherer Dinge gerne den Fehler, das Genie des Volltrottels zu
unterschätzen.
