No, it doesn't prohibit non-ASCII in DNS. It only say that labels which pass ToUnicode function are legal IDN names and that other labels which start with the ACE prefix SHOULD be avoided. It is very explicitly stated this way so (a) IDN version 2 (whoever dare to talk about it) can use a different ACE prefix and (b) some different binary encoding of whatever charset can be used in labels. IDNA does NOT change the definition of DNS labels. It only says that labels with a specific prefix are said to be "IDN labels". paf
