And metrics are off, the distance between the first triangle and the aaa to the right is actually only one space.

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.
