Tests if hostname contains segments with an ASCII-compatible
encoding of an Internationalized Domain Name. If this returns
TRUE, you should decode the hostname with g_hostname_to_unicode()
before displaying it to the user.
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.
