This is just like SSL support, needed for DNSSEC and TSIG, except that most operating systems don't already ship with libidnkit.

All I know is what you find in the BIND source code directory. For example, with BIND 9.7.0b2:

$ ./configure --help | grep idn
  --with-idn=MPREFIX      enable IDN support using idnkit default PREFIX
  --with-idnlib=ARG       specify libidnkit

$ less README.idnkit
