In that case, I think the source of the problem is that the
command prefer-coding-system doesn't satisfy this request of
yours:
Prefer utf-8 only in automatic detection on reading a
file, not for the other situations.
(defun prefer-coding-system (coding-system)
"Add CODING-SYSTEM at the front of the priority list for automatic detection.
This also sets the following coding systems:
o coding system of a newly created buffer
o default coding system for subprocess I/O
This also sets the following values:
o default value used as `file-name-coding-system' for converting file names.
o default value for the command `set-terminal-coding-system' (not on MSDOS)
o default value for the command `set-keyboard-coding-system'
How about changing it to skip "This also ..." parts if
called with a prefix argument?
Then, on writing, if buffer-file-coding-system is not
locally bound, default-buffer-file-coding-system is tried
automatically.
And, for the case that buffer-file-coding-system is locally
bound differently from default-buffer-file-coding-system,
but it can'd encode the current buffer, we can change
select-safe-coding-system to try
default-buffer-file-coding-system before trying the most
preferred coding system.
That way, I think we can satisfy your request completely.
