Domain mapping dont work with umlaut Domains


i use your domain mapping tool. But it dont work with german umlauts. so we have in some words äöü (aou).


Dont work.

When I logged in as a administrator and I visite http://www.example-mü => wp will create a new site:

in the domain mapping tool I added example-mü

or should i add the punycode of the domain? But could you tell me what is the punycode ?
