Domain names appearing in message headers, SMTP commands, URIs, etc. are
required by various standards to contain only ASCII letters, digits,
hyphens, and dots.  Therefore there is no telling what existing software
would do if faced with domain names containing other characters.  Some
of it would surely break.  DNS is not the problem.
