Dear Dave,
Two comments:
1. The TC/SC problem or variant problem comes from Unicode and the
decision
to adopt Unicode as the basis to develop IDN technology. If the
working
group chooses to use Unicode as basis, then it becomes a partial
solution
to the "global" IDN problem because of this side-effect.
2. We do not want to delay your process either. Please refer to the
draft
"Phased Implementation of Internationalized Domain Names in
Applications"
for more details.
