23.0.60; (message-check 'illegible-text ...) fails on eight-bit chars |

Gnus/5.110011 (No Gnus v0.11) Emacs/22.1 (gnu/linux) |
Package: emacs,gnus
Version: 23.0.60
When replying to an article with a bogus charset declaration
(e.g. charset="ISO 8859-15" produced by Knode; "ISO-8859-15" would be
correct. An example in gmane.test is
<address@hidden>) with Gnus, the buffer
contains eight-bit-control characters.
When sending the reply, Gnus asks: "Use ASCII as charset? " (see
`mml-parse-1').
Option 1: Answer `y'.
Result: The reply is sent with charset=us-ascii, but it contains 8bit
characters.
Option 2: Answer `n'. The Gnus asks a second time. Answer `n' again.
Result: The same as above.
See <address@hidden> in gmane.test
Expected behavior:
This following code from `message-fix-before-sending' should kick in:
(This is what happens in Emacs 22 with current Gnus CVS trunk,
i.e. the same Gnus code base as Emacs 23.)
(message-check 'illegible-text
(let (char found choice)
(message-goto-body)
(while (progn
(skip-chars-forward mm-7bit-chars)
(when (get-text-property (point) 'no-illegible-text)
;; There is a signed or encrypted raw message part
;; that is considered to be safe.
(goto-char (or (next-single-property-change
(point) 'no-illegible-text)
(point-max))))
(setq char (char-after)))
(when (or (< (mm-char-int char) 128)
(and (mm-multibyte-p)
(memq (char-charset char)
'(eight-bit-control eight-bit-graphic
control-1))
(not (get-text-property
(point) 'untranslated-utf-8))))
(message-overlay-put (message-make-overlay (point) (1+ (point)))
'face 'highlight)
(setq found t))
(forward-char))
(when found
(setq choice
(gnus-multiple-choice
"Non-printable characters found. Continue sending?"
`((?d "Remove non-printable characters and send")
(?r ,(format
"Replace non-printable characters with \"%s\" and send"
message-replacement-char))
(?i "Ignore non-printable characters and send")
(?e "Continue editing"))))
(if (eq choice ?e)
(error "Non-printable characters"))
(message-goto-body)
(skip-chars-forward mm-7bit-chars)
(while (not (eobp))
(when (let ((char (char-after)))
(or (< (mm-char-int char) 128)
(and (mm-multibyte-p)
;; FIXME: Wrong for Emacs 23 (unicode) and for
;; things like undecable utf-8. Should at least
;; use find-coding-systems-region.
(memq (char-charset char)
'(eight-bit-control eight-bit-graphic
control-1))
(not (get-text-property
(point) 'untranslated-utf-8)))))
(if (eq choice ?i)
(message-kill-all-overlays)
(delete-char 1)
(when (eq choice ?r)
(insert message-replacement-char))))
(forward-char)
(skip-chars-forward mm-7bit-chars)))))
In Emacs 23, (char-charset char) returns `eight-bit'. Is adding
eight-bit next to eight-bit-graphic sufficient? The comment (by Dave
Love, CC-ed if I got X-Debbugs-CC right) seems to suggest that there's
more to be done.
Bye, Reiner.

Ok. Well, I think it may (or may not be) nice to warn users about
sending un-encodable bytes. But they will most likely get a warning of
some kind, since there's probably other eight-bit-chars there, so I
think that's probably sufficient. So I'm closing this report now,
unless anybody objects...
