That's true, but there is no standard character representation for
octet values 128 - 255.
utf-8 is the one used in the ietf community.
I challenge you to find a RFC that say it is UTF-8.
Only octets in the range from 65 to 90 (uppercase) and 977 to 122
(lowercase) have a case equivalent for DNS resolution.
dns resolution is eight bit clear.
It may be 8 bit clear but only 0-127 have defined meaning.
128-255 may be UTF-8 but they could equally be ISO-LATIN-*.
