I had all these installed, visible to FontBook, but none of my attempts 
to use them from within my code worked.  So I uninstalled them to do some 
clean experiments.  And I must not quite have my head wrapped around "in 
Unicode encoding" yet.  That means the sigma glyph is accessed using 
something other than a character code of "58, that's for sure.  I'm 
working at a pretty low level here.

I will experiment with the Latin Modern fonts after installing them.  But 
once installed, it's still unclear to me how I refer to that Latin Modern 
font corresponding to what TeX uses for the summation glyph.  Do these 
fonts have a different character-code-to-glyph-mapping from what TeX 
uses?  If not different, that's one thing less to warry about.

Thanks!
