[kitsune@vixen42]/home/kitsune% ping \U+1F4A9.ws
ping: cannot resolve 💩.ws: Unknown server error
Neither does ping on Linux.
Should it, at least by default (without a flag)?
Regardless of if a flag is being passed or not, it likely would be a good idea to support IDN, even if a flag is required.
On another note, traceroute does not like unicode characters as well.
[kitsune@vixen42]/home/kitsune% traceroute \U+1F4A9.ws
traceroute: unknown host 💩.ws
I ran into this issue too on RELEASE-12. I can add /usr/bin/host to the list. I noticed that WITH_BIND_IDN has been removed as an option for /etc/src.conf which used to make this work in older versions (before 10 I think).
