I succeded in makeing a virtuel domain with the name: "xn--kohullet-44a.dk" wich is the IDN-form af "økohullet.dk" translated with the form at:
http://api.webnic.cc/idnconversion.html.
If your problem is the length of the name you can change it with this info:
In order to provide compatibility with Windows9x machines we have deliberately set these limits to twelve. You can change the maximum length of these by setting maxIbayNameLength, maxAcctNameLength and maxGroupNameLength. When unset the default is 12. To allow names as long as 15 characters for an ibay for example, execute the following commands:
/sbin/e-smith/db configuration set maxAcctNameLength 15
/sbin/e-smith/signal-event console-save
Ater installing the plugin for InternetExplorer from Verisign:
