Oops, this was supposed to be a private reply ;) - sorry about the
noise. The essence in English:
JGR uses all strings in UTF-8 encoding, but the system locale reports
CP1252 which impedes automatic conversions (because R doesn't know
that everything is UTF-8). Specific conversion via iconv works as
expected (see the example below).
Cheers,
Simon
