(4) "works" is misleading, it is wrong if it "works".

It is a VERY DANGEROUS BUG in RFC 3987, incompatible
with the spirit of STD 63 and DNS.  

The label "B%C3%BCcher" could exist, not at the 
level in your example, because DENIC won't allow
it, but at other levels or in other zones.  

And it is totally unrelated to "xn--bcher-kva",
unless the owner of "B%C3%BCcher" arranges it as
alias for "xn--bcher-kva".

IMO the IE7 behaviour "doesn't work" is perfect,
the FF3 / safari behaviour is completely broken.

BTW, FF2 also gets it right, like IE7, it won't
arrive at "buecher.de" for "B%C3%BCcher.de", but
does the right thing for the <http://bücher.de>
IRI and the IDNA <http://xn--bcher-kva.de> URI.
