hg attempts to convert an already utf-8 string from the user locale
(ascii) to utf-8.

HGENCODING=UTF-8 fixes this of course, as UTF-8 was guessed from my
$LANG=fr_FR.UTF-8

The problem is that the encoding is specified by the patch itself and
not by the user environment.

What to do here?

If I use encoding.tolocal() there's no crash anymore but instead of
'ë' I see '?'
