    They default to bd=L. From DerivedBidiClass-4.0.1.txt:

    E000..F8FF ; L # Co [6400] <private-use-E000>..<private-use-F8FF>

    Of course an application can do whatever it wants with
    the properties of private use characters, but if you are
    dependent on someone else's implementation of the
    bidirectional algorithm (as will be the case for most
    people building applications on Windows), then you define
    right-to-left private use characters at your own risk
    and probably (as you have found out) to your own great
    frustration.
