I'm not convinced mine has failed. For one, the diacritic and root
character are not side-by-side. Perhaps I'm wrong, but if they were truly
side-by-side, wouldn't I be able to put point on either the accent or the
root character?

Here's how to make ñ compositionally:

n C-x 8 <RET> 0303 <RET>

Could you run describe-char on a compositional character and post the
results? I want to see how it differs from my output. (Presuming, of
course, that your emacs renders them correctly :-)

Thanks for the patches. I've applied them to the 24.1.1 source but make
segfaults when compiling profile.c. I don't have the time to fix this
unfortunately.

I presume you use emacs on OS X? Did you build it using this patch? Do
compositional characters work? Further, if you have the time, could you
build the regular source --with-ns and see if they work there? Perhaps the
issue is with my OS.

Cheers,
