Nice.  Basically, unless the TLD registrar has a public policy that basically says
"We don't allow names with cyrillic C to collide with MICROSOFT", their hostnames
all get displayed as xn--gobbledygook.

(The actual policy for the .UA registrar is more subtle. They *do* in fact
allow "U+0441 Cyrillic Small Letter ES" which is visually a C to us Latin-glyph
users.  However, they require at least one character that's visually unique to
Cyrillic in the domain name.  They also don't allow mixed Cyrillic/Latin
scripts in one domain name).  Or so http://www.hostmaster.ua/idn/
tells me after Google Translate gets done with it. ;)

If the manufacturers of IE and Safari can't come up with a similar policy,
then the people at Mozilla can use "We protect you from malicious names"
as a marketing diffferentiation feature.
