Instead, conversion to A-label form, or any other special encoding
required by a particular name-lookup protocol, should be done only by
an entity that knows which protocol will be used (e.g., the DNS
resolver, or getaddrinfo() upon deciding to pass the name to DNS),
rather than by general applications that call protocol-independent
name resolution APIs.
Wow. This change would both be incompatible with 4871, and would put
non-ASCII 8-bit characters into DKIM-Signature: headers, thereby making
them invalid under RFC 5322 and getting them smashed by any 7bit MTA.
So, let's not do that.
