Not that I know of, but aren't they supposed to just be UTF-8?

No, they are encoded using Punycode:

http://en.wikipedia.org/wiki/Punycode

With a quick search for "ruby punycode", I found:

http://raa.ruby-lang.org/project/punycode4r/

And it seems to work:

Punycode.encode(Iconv.iconv("UCS-4LE", "ISO-8859-15", "b=FCcher")[0])
=3D> "bcher-kva"

(From the wikipedia article: "b=FCcher.ch would be represented as =20
xn--bcher-kva.ch in IDNA")

Punycode.encode seems to expect "UCS-4LE" encoded strings.

HTH,
Dominik
