Japanese/German domains and URLs

#1

We have landing pages that are in JP and DE languages and want to be able to use a JP or DE domain/URL such as http://試す.imperva.com/デモ. Is this possible to set up in Unbouce? When adding the domain it says it is not a valid domain and when changing a page URL it does not accept it and just sets it to the default URL. Any insight on this would be great.; Thank you.
