    Combining marks have neutral bidi properties, and several other
    properties, and so inherit these properties from their base characters.
    Would this apply also to PUA characters used as combining marks? This
    would of course be necessary if these combining marks are to be applied
    to RTL scripts.

    By the way, since there are such neutral properties for combining marks,
    surely these would be more suitable defaults for PUA characters as well,
    better than the existing defaults which specify particular properties
    which are useful for some but useless for others.
