I think this is a type. SASLprep is case-preserving, and hence may not be appropriate for the user portion of a UPN, if the latter are intended to be case-insensitive. > I also think it > odd to allow both toUnicode and toASCII domain component > forms on the wire. So do I. > (I recommend the latter). Why? The toASCII form was designed to allow IDN's to be encoded for use in protocol fields which are very restrictive about what octet strings they can carry; in particular, label fields in the DNS wire protocol. Why do I keep seeing people who insist on using that inefficient encoding in protocol slots which are perfectly capable of carrying UTF-8? That's very much like suggesting the use of base-32 encoding in an 8-bit-clean field. Use of toASCII is appropriate for _existing_ IDN-unaware uses of domain names. I wish someone would explain to me why so many people want to use it for IDN-aware uses in new protocols. -- Jeff _______________________________________________ Ietf mailing list Ietf@ietf.org https://www1.ietf.org/mailman/listinfo/ietf
