The gethostbyaddr() OS function returns a byte string with no specified
encoding. Python 3 will doubtless try to decode that to a character string
using some (probably unspecified) encoding.

Names obtained from DNS should consist entirely of ASCII characters
(gethostbyname shouldn't attempt to decode internationalised names
which use IDN, it should return the raw data).

Names obtained by other means (e.g. /etc/hosts or Active Directory) could
contain anything, but if you use non-ASCII hostnames you're asking for
trouble.
