Tests if hostname contains Unicode characters. If this returns
TRUE, you need to encode the hostname with g_hostname_to_ascii()
before using it in non-IDN-aware contexts.
Note that a hostname might contain a mix of encoded and unencoded
segments, and so it is possible for g_hostname_is_non_ascii() and
g_hostname_is_ascii_encoded() to both return TRUE for a name.
