I think we might have to use just regular letters, unless more common symbols are found.

This question will probably arise with other characters too, which are not present in each font, like superscripts, subscripts, and some mathematical symbols. But I think we have no other choice here.

I think all the characters I used are present in the Arial Unicode that comes with all Windows OS, and I believe Linux and other OS's have an equivalent one.
The math symbols are more specialized, though, it's harder to find a good font.

The main difference in newRPL, is that I have to do ENTRY twice to return to the Program mode, which represents 4 key presses, and it's not very convenient. Could it be changed to one ENTRY only?

I'll see if I can make it better. Ideally, it should switch modes automatically, but that could make it slower, since for instance a long program might need to be analyzed completely to determine if programming mode needs to be active (the opening bracket could be quite far).
