Yes it should.  In fact, Unicode says that they should be equivalent, and a
good implementation will probably substitute the single glyph equivalent
(&#x226f) rather than overlay the "/" on a ">".  However, as you have found,
the support for combining chars in MathML applications is not very common,
so I would stick to using &#x226f (&NotGreater;) if possible.

As Paul just remarked, we are working on combining character support for
MathPlayer and it should be in a not too distant release (for arbitrary
values of "not too distant":-)
