Subject: Saving safe local variables garbles 8-bit characters in .emacs file

- --=-=-=

Under certain circumstances saving safe local variables permanently,
i.e. answering with `!' to the respective question may garble 8-bit
characters in a .emacs file.  For this to happen the .emacs file has
to contain UTF-8 characters and has to be saved as UTF-8.  In addition
Emacs has to be started in a directory with a .emacs.desktop file
which has to load a LaTeX file containing 8-bit characters like
umlauts, i.e. a file with a Latin-1 coding system.  In addition the
LaTeX file has to contain a Local Variables section with an unknown
variable.  As soon as Emacs is started this should pop up the question
about how to deal with the variable and once you answer with `!' the
.emacs file will be written.  If you open the .emacs file after that
8-bit characters will be garbled (it looks like the UTF-8 characters
got decomposed into their two separate bytes).

Attached you can find the files I used for testing (".emacs.orig" is
the original .emacs file and ".emacs.result" the one after the safe
variables stuff was written to it):
