You're not alone, I would really appreciate such functionality too, but I
understand that it is not easy. Imagine the number of symbols that people
might want to include, you already mentioned the Greek alphabet, and
accents on top of them, add to that all the symbols in bold (for matrices),
subscripts and superscripts, and all kinds of operators, and it should work
fine on Unix, Mac, and Windows.
Oh, you mean like LaTeX?
