What IDN support means is that the resolver accepts the actual names,
not just the punycode encoding of them. So that, like, you can type
ping 納豆.w3.mag.keio.ac.jp and have it work without ping having to
link some 3p library.
The WIP proposal for implementing it canonicalizes both the input and
the entries in the hosts file to punycode before comparison so that it
works consistently regardless of whether you have unicode literals or
punycode in your hosts file.
