Only by means of blocking registration. A registration can be blocked
not only because it violates static rules, but also because it is
(or could be) a homograph for a different, already registered, label.

This is indeed the case already in .COM for Chinese labels: registration
of a single label blocks an entire family of labels - not necessarily
homograph ones, but labels that Chinese readers would consider "same".
