Certainly (IDN was invented for a reason). The Web page
http://cr.yp.to/djbdns/idn.html shows an awful ignorance of both
Unicode and DNS.

PS: we (".fr" registry) recently received a bug report like that:

Dec 8 13:09:47 mastermind pdns[23171]: Received a malformed qdomain from X.Y.Z.T, 'SUIVI MATERIEL.local.fr': dropping
Dec 8 13:09:50 mastermind pdns[23171]: Received a malformed qdomain from X.Y.Z.T, 'www;pajemploi.ursaff.fr': dropping
Dec 8 13:10:09 mastermind pdns[15986]: Received a malformed qdomain from X.Y.Z.T, 'cédric.local.fr': dropping

So it seems that PowerDNS has trouble, not only with 8-bits characters
but with legal DNS ASCII characters like the semicolon, as well.
