James,
you are right. But this is the basic problem of using Unicode.
Unicode documents character sets in typesetters (typography) and not
visual character sets in human contexts (orthotypography). There are
two solutions to this.
1) to get rid of Unicode. Unlikely.
2) to use an Man/Unicode conversion algorithm and to use the living
Man (who in addition may evoluate) as a reference instead of the
machine's history (which is also updated).
IDN tables are a limited temporary patch to such an algorithm. We
come back to the RFC 4647 issues ..."what is a language". As long as
this XXe century cross-discipline question is not addressed we will
never know for sure that a cyrilic o in an .au domain name and in an
Australian gTLD are treated the same.
