One problem with the Windows port of Emacs is that some of the Windows
output routines do logical-to-visual reordering internally. Try
displaying etc/HELLO on Windows in an unpatched Emacs 21.x and look at
the Hebrew greeting: it will be displayed correctly in visual order,
right to left, even though Emacs sent the logical-order string to the
display! Now move point with C-f across the Hebrew greeting, and you
will see it displayed in the logical order(!).
So I expect some problems with bidi Emacs on Windows. The
Windows-specific display code should somehow disable the automatic
reordering performed by the Windows runtime.
