#17146 (this bug) is no longer present in the current pretest. So I'm
going to mark this bug "done".

This part of the discussion should probably be elsewhere, maybe in
#17109, maybe in a separate bug report (with new details about the
signs of damage you see in your code).
[Message part 3 (message/rfc822, inline)]
On trunk:
emacs -nw -q file.txt
M-: (insert "μ\xc1")
C-x C-s
This throws a "make-text-button" error "Unknown button type
`help-xref'". And it doesn't save. I believe it should ask which
coding system I want to use to write to disk.
