Have you tried it?  It's not a valid entity, using it means your XML is
not well-formed.  It doesn't matter whether you say � or � (the
decimal and hexadecmial forms are exactly equivalent - but 0 is still
not a validnumerical entity.)

As long as you can read the same data back and restore the same sequence
of bytes it doesn't really matter.
