UTF-8 is a standard. MS products have used two-octet chars to support Unicode for a long time. Any reason to add yet another encoding?
UTF-8 is a character encoding standard, not a DNS-standard. DNS is not, and has not ever been 8-bit clean, despite the fact that many, if not most, implementations will survive UTF-8 labels. IDN(A) is an effort to encode unicode into 7-bit DNS-labels, without breaking backward compatibility (too hard). While there originally were a few voices arguing for UTF-8 over the wire, they were few and the consensus today is that IDN(A) is a Good Way to Go(tm).
How about encouraging widespread adoption of EXISTING standards instead of adding more cruft? UTF-8 is standard. Proper DNS implementations are eight-bit safe. People upgraded browsers due to SSL, Year 2000, Javascript...
Or, how about encouringing widespread adoption of upcoming standards, such as IDN? http://www.ietf.org/html.charters/idn-charter.html Remember, DNS implementations may be 8-bit safe, but that doesn't prevent anything else from not being so. Domains are used in so much more than DNS, you know. =) Best regards, Kandra Nygards
