bug#24741: 25.1.50; Buffer encoding corrupted up by 'make' in shell-mode

[Simon Peyton Jones]

Thanks everyone.  It's a bizarre bug!  But it's one that does make my life a 
lot worse, because my compiler's error messages are littered with quotes, each 
of which turns into 12 characters of encoding, as you can see.

If you want me to try emacs -Q, just let me know how to do that and what info 
to collect.  I've never done that before.

Customisations. In my .emacs I have the following, which John Wiegley gave to 
me in the first place

(setq-default locale-coding-system 'utf-8-unix)
(setq-default buffer-file-coding-system 'utf-8-unix)
(set-default-coding-systems 'utf-8-unix)
(set-terminal-coding-system 'utf-8-unix)
(set-keyboard-coding-system 'utf-8-unix)
(set-selection-coding-system 'utf-8-unix)
(prefer-coding-system 'utf-8-unix)

(defun utf8-shell ()
  (interactive)
  (set-default-coding-systems 'utf-8-unix)
  (shell))

(setq w32-get-true-file-attributes nil)

Simon

|  Actually, posting here the relevant parts of Simon's customizations
|  (the ones that are related to coding-systems and to running shells)
|  might also help identify the probable causes.
