Okay, I believe I fixed the following, by making sure strings
were being treated as strings (adding NUL '\0' at the end,
which was missing sometimes!)

However, the compose problem still seems to be in effect.

So right now, if I type: ['] [a], I get "�", rather than "'a",
even without first clicking the [Cmp] (compose) button.
This is not the correct behavior.

(And, of course, typing ['] at first appears to do nothing.
If I type it again, I finally get a "'" on the screen.)

Again, this is all with the On-screen Keyboard feature
(tuxpaint --onscreen-keyboard).  Typing on my physical keyboard
seems fine.  (i.e., it's a problem at the OSK level, not the
IM level, like I mistakenly stated before.)


So...  OSK experts (Pere? maybe Mark?), what do you think?
I've tried doing a diff between 'master' and 'sdl2.0' branches'
versions of "onscreen_keyboard.c" and am not finding anything
obvious. :-(

Thanks in advance!
