I don't see how a name resolution API returning non-ASCII bytes
would indicate an error. If the host table contains a non-ASCII
byte sequence for a host, then that is the host's name - it works
just as well as an ASCII name, both forwards and backwards.
What is hackish is representing char * data as a Unicode string
when there is no native Unicode API to feed it to - there is no
issue here such as file names being bytes on Unix and Unicode on
Windows, so the clean thing to do would be to return a bytes
object. I suggested the surrogateescape mechanism in order to
retain backwards compatibility.

But to be more explicit, that's like saying "if it hurts, get
your sysadmin to reconfigure the company network".
