Technically, with BIND one could configure a stub zone for "xn--55qx5d". 
Or a slave zone, if the authoritative servers allow zone transfers 
(which, according to a trivial test I just ran, they do not). Of course, 
it might be tedious to configure and maintain stub/slave definitions for 
all of these "alternative" TLDs...
