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-*.
