Avoid ISO-8859-1 character in fr.po header.

Python 3 gettext can handle arbitrary character sets for the messages
in .mo files, but always tries to decode the header information as
UTF-8.  This means that using the French translation fails because it
tries to decode b'Last-Translator: St\xe9phane Raimbault
<[email protected]>' as UTF-8, when that is an ISO-8859-1
string.  Fixed by avoiding the accent in that string to make it pure
ASCII.  Alternatively, all the remaining non-UTF-8 translations might
reasonably be converted fully to UTF-8.
