I'm not sure what you mean by “not really”.  Are you saying you
dislike my idea that “=” could do the same as “+”?  For my keyboard,
“=” is a much better character to use because it doesn't require using
the shift key.  It would remind me of “+” because it is on the same
key.

I think they probably are, but it needs invoking the right functions.

A quick look at the libsdl documentation installed on my computer at

  file:///usr/share/doc/libsdl1.2-dev/docs/html/guideinputkeyboard.html

makes me think that the “unicode” field of the key event will hold the
right information provided the SDL_EnableUNICODE function is called at
initialization time to ask SDL to convert key events into characters.
