Which is what I said was happening in comment #11.

nsfont.m has problems with composition, there is even comments about this in
the code.
But from what I see on X11 and what you reported from W32, no other platform
does produce the correct result (i.e. the ! and the triangle in the same
place), so comparing to those backends doesn't help.

Adding more pictures does indeed not help much.
