In practice I expect that should work, but IIRC a strict reading of the
C++ standard would suggest that it leaves the behavior for values from
_HB_SCRIPT_DUMMY2 to 0xFFFFFFFF undefined, as they're not part of the
range of the enum's values. It's hard to imagine that a compiler would
do anything too weird with it, however.
