installing wordpress on idn domain

hey forum

my blog is already up and runnin here http://www.xn--hnerbein-65a.de/. I’ve got a question regarding compability to idn domains.

The domain I registered is http://www.hünerbein.de … some browser accept this domain like firefox some dont like IE.

One can reach the blog via Firefox http://www.hünerbein.de but whenever I click on any link the domain changes to http://www.xn--hnerbein-65a.de/.

Is it possible to configure wordpress to http://www.hünerbein.de? Or is it not supported yet?

Im looking forward to your answers. Thanks go out to the dev’s!
