Yes, ping does not parse idn hostnames, this post is about BIND related tools. ping makes no use of them.
To fix ping:
- Port it to use unprivileged ICMP sockets. so the binary is no longer ever running with elevated capabiltiies (cap_net_raw in current products, setuid root in other releases) and the risk of linking another library (in this case idnkit or whatever) is lowered.
- make it understand IDN with such library.
- profit :-)
