    I know that they have default values. That's not the problem and not the
    question which was:
        How to get a Bidi OVERRIDE with PUAs?
    The term OVERRIDE is important here.

    I just wonder why I can't force this property notably on PUAs where the strict
    BiDi rules SHOULD be relaxed, and what I could do to get a RTL presentation of
    these characters. I never said that IE was not conforming, but that PUAs which
    can't be defined for RTL characters are a great source of "frustration" as
    Kenneth said.

    Isn't there a format control that works to _force_ a RTL behavior on PUAs (or
    other characters...)?

    Should then I use non standard assignments in reserved areas or over an existing
    RTL block, so that my doc would no more be conforming to the encoding model?
