As well as the many logographic characters that can be interchanged in
some limited ways, with conditions, and will not fit with the strict open
model needed by Unicode as they may be covered by copyrights or
digital rights. The existence of these restrictions, which limits, but in
does not forbid interchanges of information is a grey area currently not
covered either by PUAs (not interchangeable), and by regulated parts
of Unicode due to its policy.
This is a place where limited agreements managed by a registration
authority could help avoid conflicts of assignments, simply not possible
