You need to turn on IDN support at compile time if you want the
lookup tools to do the name conversions prior to looking up the
data in the DNS.

  --with-idn=MPREFIX      enable IDN support using idnkit default PREFIX
  --with-libiconv=IPREFIX GNU libiconv are in IPREFIX default PREFIX
  --with-iconv=LIBSPEC    specify iconv library default -liconv
  --with-idnlib=ARG       specify libidnkit

As far as named is concerned these are just regular domain names
that start with "xn--".  All the IDN knowledge is outside of named.
