There shouldn't be any non-ascii in a mbox. Well, maybe in a
"Content-Transfer-Encoding: 8bit" (or binary?) body part, but certainly
not in any headers.

I don't know what you are grepping, but if it's the mbox, you shouldn't
be looking for "\xea", you should be looking for "ê".

Are you running bin/arch with the --wipe option? If not, you are
repeatedly adding the same messages to the archive which is why the
number increases.

Probably not.

Python's default encoding could make a difference if it was something
other than ascii previously.
