My interpretation is that there are no restrictions at all after ".alt". (I 
assume ".alt" should be in a format that DNS resolvers / servers understand).
I can see the pros and cons of this approach.
Implementing any kind of restrictions will open pandora's box wrt registration 
policy / reviewer considerations.
Not having any kind of restrictions will leave the registry open to strange 
requests like the ones you highlight.
I think you have pick one of those evils.

Also:
Given that it is unknown what encoding a protocol may use, it may be reasonable 
to consider that instead of Unicode, a byte string is provided with an optional 
encoding hint?
For GNS, Unicode/UTF-8 would work fine, however.
