Back to 1999, the W3C Internationalization Working Group advised other
Working Groups not to add new character entities in W3C specifications.
Following that advice, the HTML WG has "frozen" the (X)HTML entity sets,
and various proposals for new character entities were rejected on that
basis.  There is a suggestion to develop a universal character entity set
for XML (not just for XHTML), but it is extremely unlikely that XHTML2
would add its own new character entities.

Opera 6/7, Netscape 6.x, Mozilla 0.9.8 and earlier, to name a few.
