Thanks for the pointers.  It seems like Mathematica has a great list of all
of the escaped characters it can put into text (along with the escape
sequence), but doesn't have a list of valid non-escaped characters.  Are
only alpha-numeric letters allowed as non-escaped characters in a variable
name?

I was looking for an EBNF definition for mathematica that might let me read
the list, but I can't find that either.
