On w32, the Uniscribe font driver does not compose these two
characters. So I guess this composition is done by the driver used by
NS, and perhaps the composition information Emacs gets is incorrect.
Once again, please show the full output of "C-u C-x =" on the composed
character, the pixel-level data of the composition shown there will
probably tell us what is wrong.
