Variable: save-buffer-coding-system
save-buffer-coding-system is a buffer-local variable defined in
files.el.gz.
Documentation
If non-nil, use this coding system for saving the buffer.
More precisely, use this coding system in place of the
value of buffer-file-coding-system, when saving the buffer.
Calling write-region for any purpose other than saving the buffer
will still use buffer-file-coding-system; this variable has no effect
in such cases.
