emacs silently ignores buffer file encoding?

emacs silently ignores buffer file encoding?

[Miles Bader]

(1) Start emacs -Q
(2) Visit "/tmp/fff"
(3) Insert the following chars: "θϑΘ"
(4) Set the buffer file encoding to latin1 with: C-x C-m f latin-1 RET
(5) Save the buffer: C-x C-s

For me, "/tmp/fff" is saved sucessfully, with no error or prompt, using
an encoding of utf-8 -- despite my having explicitly requested latin-1.

This doesn't seem right...

Indeed, please post it to the bug-tracker: IIRC this has been reported
before, but got lost.

How does one post to the bug-tracker?  Is sending to emacs-pretest-bug enough?

Thanks,

The same way as you always did. [etc...]

I agree.  I'll work on it if nobody else is working on it.

I've just installed these fixes:

2009-03-03  Kenichi Handa  <handa@m17n.org>

	* files.el (basic-save-buffer-1): Set car part of
	buffer-file-coding-system-explicit.
	(revert-buffer): Check car part of
	buffer-file-coding-system-explicit.

	* international/mule-cmds.el (select-safe-coding-system): If cdr
	part of buffer-file-coding-system-explicit is set, ignore
	default-buffer-file-coding-system and the most preferred coding
	system.

	* international/mule.el (set-buffer-file-coding-system): Set cdr
	part of buffer-file-coding-system-explicit.
	(after-insert-file-set-coding): Set
	buffer-file-coding-system-explicit to a cons.
