    The ZWARAKAY has been approved for encoding by the UTC:


    It still has to wend its way through the ISO ballotting process,
    so it is a couple years away from final publication, at this

    The UTC hasn't considered the AFGHANI SIGN yet, but there is
    no reason to think that it will be controversial when it comes
    up in a formal proposal.

    These are just two more examples of legitimate characters,
    fairly recently identified, that will take awhile to be
    standardized in a particular (future) version of the Unicode
    Standard. Implementations which need to use them *now* may,
    as Michael has suggested, make use of PUA encoding, in the
    knowledge that once standardization is complete, they will
    have to shift their representation to the standard code points.
