RFC 2277, "IETF Policy on Character Sets and Languages", section 3.1,
"Protocols MUST be able to use the UTF-8 charset [...] Protocols MAY
specify, in addition, how to use other charsets [something DNS does
not do, so it must be UTF-8]"
(ooh.. an RFC lawyering fight. Goody goody, haven't had one in a while.. :)
That requires overlooking the minor detail that the DNS RFC predates that by quite
some time, and there's no combination of RFCs 2119 and 2277 that mandates
retrofitting grandfathered protocols by fiat.
It also requires overlooking the fact that 2277 is a BCP, not an Internet Standard, and
as such isn't itself binding, merely A Good Idea.
Nice try though. ;)
