You're right, of course :-(
Which proves how ugly all this IDN stuff is. It's an example of what you
get to when the standards confuse machine-readable names with names to
be shown to the user. (Or what happens if user demands take precedence)
You really, really, really don't want to have to deal with
case-insensitive Unicode strings. That's a can of worms. Just saw this
again with Thiago's example:
% ~1/test www.fuß.de
www.fuss.de = www.fuss.de
(Hint: it's not reversible) or with the famous Turkish i vs I (Hint: I
is not uppercase i in Turkish; uppercase i is I with a dot above).
RFC 2822 was very nice in this respect: the addr-spec was
machine-readable and restriced to a subset of US-ASCII and all
internationalization happened outside of it, in the display-name, which
was not case-insensitive nor even interpreted in the first place.
