dns itself is purely eight bit transparent. one can even have a dot as a non-separator. p.r.c could be a tld. it's strictly length/value. 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.
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. randy
