    I assume this project makes use of the "special protocols" mentioned in
    the standard. Otherwise that seems like a rash expenditure.

    No assigned characters are ever removed from Unicode. (I assume you
    meant that rather than "code points.")

    There was a proposal to deprecate the Plane 14 tags; indeed, it was the
    very first Public Review Issue. The UTC decided not to go quite that
    far. Really, no opinions have ever changed that much regarding the
    Plane 14 tags. They were born as the red-headed stepchildren of
    Unicode; they were created only to prevent a particular protocol from
    using a mutant form of UTF-8 for language tagging.

    Whether Microsoft implements something is not up to the UTC or the
    Unicode Consortium.

    This list does not appreciate being set up or baited. Sorry.
