Re: Auto-detection of windows-1252 fails

[David De La Harpe Golden]

[this is more appropriate place to note this than the thread Reiner+I
were in in comp.emacs]:

Function set-coding-system-priority in src/coding.c
says it won't actually add two encodings of the
same "coding-system-category" to the priority list.  And at least in
emacs-unicode2, iso-latin-1 and windows-1252 are apparently being put
in the same category, "coding-category-charset", unlike, say utf-8 or
sjis.  So adding windows-1252 to coding-priority after iso-latin-1
won't do anything without changing more stuff.

main and emacs-unicode2's src/coding.c look like they differ quite a bit
at this stage, but on emacs-unicode2 (I personally don't have a cvs
head version around at the moment to check what it's doing):

(mapcar (lambda (x)
                (cons x (coding-system-category x)))
        (coding-system-list)) ;; or just '(windows-1252 iso-latin-1))

shows that a lot of encodings are ending up in coding-category-charset.
