Jumping in...

There are some domain name registries that prohibit certain combinations of
characters in the name spaces they administer.  The administrator of the .us
ccTLD, for example, prohibits use of the seven "dirty words" described by
the US FCC and George Carlin.  While this isn't a restriction on the set of
valid characters, it _is_ a restriction on how they may be combined.  I read
Erik's note to mean that registries may well prohibit certain Unicode code
points or combinations of code points for various policy or legal reasons,
and I'd agree with that assessment.

Please correct me if my interpretation is wrong, Erik.
