The reason IDN support in the BIND query tools (dig, host, nslookup) is not the default is because it relies on a 3rd party library, which must be installed and configured by the package builder beforehand. This is just like SSL support, needed for DNSSEC and TSIG, except that most operating systems don't already ship with libidnkit.
