Correct. In Unicodese, same characters, different glyphs (to the extent
that the AMS math font canonical glyphs differ). U+2322 and U+2323 were
encoded explicitly for the frown and smile symbols, and have nothing to
do with the smily faces (unless you consider them the result of the
fading of the respective Cheshire cats). :-( :-)
