Not necessary if the document character set is a superset of the mime=
character set, and if the client can convert from the mime= character
set and encoding into the document character set.

Or a superset of them that they can be mapped into.

This is certainly possible. If the document character set is defined
to be Unicode, and the entity manager, or something below, can map
from that encoding and character set into Unicode, then all will be
well.
I would recommend taking a look at the Extended Reference Concrete
Syntax that Rick Jelliffe (ricko@allette.com.au) recently sent out.
