It seems clear from the behavior of web browsers that the Right Thing is to
convert all IDNs to Punycode before putting them on the wire.  By the same
token, all non-ASCII characters in other parts should be UTF-8 encoded and
then %-encoded before transmission.  This applies both to IRIs entered by
hand and IRIs appearing in links.

I'm pretty sure this is because no punycoding is being done in the DNS, and
it's probably getting the UTF-8 encoding instead of "
xn--gmeaux-bva.bortzmeyer.org".  When I ask Lagrange to connect to the
punycoded form explicitly, your server does not recognize it as "self" and
replies with "Proxy Request Refused".

I can't account for the behavior of the other servers easily.
