Paul,
Thank you for your replies:
One more time with feeling: please take this discussion to the IDN
WG's mailing list. It has no place on the main IETF mailing list
I understand your perspective as the authority on ACE, but UTF-5 and
competing representations are not limited to domain name applications.
For example, email user-names and URIs both face very similar issues:
what if your multibyte representation produces syntactic elements such
as "@" or "/" respectivly?
Is there an Internet Draft describing the differences between the two?

ACE would be so much friendlier if the fatal error required when an
ASCII-capable representation is encountered were softened to the simple
return of the corresponding ASCII string.
Cheers,
James
