(that's btw example from documentation)
however, it seems that it should work
http://tools.ietf.org/html/rfc3490
The ACE prefix for IDNA is "xn--" or any capitalization thereof.

A decoder MUST recognize the letters in both uppercase and lowercase
forms (including mixtures of both forms). An encoder SHOULD output
only uppercase forms or only lowercase forms, unless it uses mixed-
case annotation (see appendix A).
