In the MathML 2.0 spec the entities: &empty; and &emptyv; are mapped 
to the same unicode number 2205, but these are different symbols in LaTeX.

empty,                     U02205, /emptyset - zero, slash, [EMPTY SET]
emptyv,                    U02205, /varnothing - circle, slash, [EMPTY SET]


Rendering in LaTEX:
  /emptyset  =  zero, slash,
  /varnothing  = circle, slash


MathPlayer 2.0 renders U02205 (empty and emptyv) as slahed circle, while Mozilla renders U02205  as slahed zero.




Is the entity &empty; mapped to the wrong unicode? 


thanks,
Bernhard
