Because those editors handle surrogate pairs. The development version of
Emacs that you are using is a work in progress, and dealing with
surrogates was marked as a TODO while more important work was done. I've
just checked in changes to deal with them, though it is untested. If you
build from CVS now, then you can help with testing, otherwise you'll
need to wait until the next build of EmacsW32 to test them.
