No, in Windows systems everything that is character-specific resides in
Uniscribe rather than the font; this includes which characters are
reordrant. Microsoft's viewpoint is that since this information is the
same for any Khmer font, there is no point in storing it in the font.
Unfortunately, Uniscribe is a monolithic object; fortunately, you can
(AFAIK) always replace an older copy with a newer one without loss of
function.
