Binary package hint: wget
wget does not support IDN domains:
$ LC_ALL=C wget 'http://www.köln.de/' --23:49:06-- http://www.k%C3%B6ln.de/ => `index.html' Resolving http://www.k\303\266ln.de... failed: Name or service not known.
Translating the URL to IDN (xn--kln-sna.de) manually works.
Maybe its possible to use GNU libidn http://www.gnu.org/software/libidn/
