Automatically Saved Files Employ Different Coding

[Alexander Winston]

Please describe exactly what actions triggered the bug
and the precise symptoms of the bug:

File the following steps and examine the diff left in the end.

M-x ucs-insert <RET> 0391 <RET>
M-x save-buffer <RET> Alpha <RET>
M-x backward-delete-char <RET>
M-x ucs-insert <RET> 0391 <RET>
M-x do-auto-save <RET>
M-x diff <RET> #Alpha# <RET> Alpha <RET>
M-x switch-to-buffer <RET> *Diff* <RET>
M-x delete-other-windows <RET>

As you can see, the automatically saved file uses a different coding,
emacs-mule, instead of the default, utf-8.
