Neither does ping on Linux.

Should it, at least by default (without a flag)?

Comment 2 Zane C. Bowers-Hadley 2017-07-31 02:49:59 UTC

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
Exit 1

Comment 3 Morgan Wesström 2019-01-21 18:37:53 UTC

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).
