I am not familiar with the product, so it unclear to me whether it it produces a UTF-8 text file with the correct Unicode code points, as is a requirement for the LuaTeX engine that ConTeXt defaults to. One can design a new key map on OS X that selects the correct Unicode code points, but that is a huge task, given the large number of math symbols.

The legacy issue is that there are already loads of TeX code that translates the Basic Latin into Unicode math italic style. So it is hard to break the habit, and old code cannot readily be reused.

And one can ignore the problem altogether, and use the traditional TeX backslash “\…” commands, but using Unicode helps the readability of the source code. This is even more so in the case of theorem proof assistants.
