Hi, and nice to meet you :-)

the option --charset UTF-8 only defines that User ID's etc should be
printed by GnuPG in UTF-8; the parameter has no influence on the
processing of the mail content.

Interesting, your signature failed too ... :-( I don't think that I'm
doing something special, I simply pass the message to GnuPG.

But could it be that the problem is not related to éàè etc, but rather
to the way the "-- " is passed to GnuPG? According to RFC 4880, spaces
at the end of a line are forbidden and will cause the signature to fail
verification. Therefore you should either sign the base64 message, or
you have to use quoted-printable if you want to have spaces at the end
of a line (and sign/verify the quoted-printable mail).
