    And the other thing to understand about this particular change
    is that it is the outcome of a years-long debate and a
    painstakingly negotiated settlement that reminded me of
    other difficult negotiations involving Middle Eastern issues.

    The upshot will be that Microsoft-based applications will
    come *into* compliance with the Bidirectional Algorithm,
    with the crucial few character property changes as stated.
    And IBM and other vendors who had implemented based on the
    prior property values agreed that it was worth the tweak
    in order to bring the entire industry into an agreed,
    interoperable state for bidirectional behavior (in the
    absence of higher-level protocols) involving the crucial
    ASCII characters, '+', '-', and '/', that interact with URL's,
    dates, times, and numbers in a bidirectional context.
