XP and Unix changes to ensure that 0-width spaces (0x200B and
0xFEFF) are handled correctly. With this we now have 2-character
ligatures working properly in the bidi-build -- the Arabic support
should be now quite satisfactory.

I am not sure what happens on Win; I suspect that the API drawing
functions handle these correctly, if not small changes to drawChar,
drawChars, measureUnremappedChar and measureString will be
necessary.
