    Briefly, the new issue is:

    Issue #96 Allowing Joiner Characters in Identifiers

    The use of format characters in identifiers is problematical because the
    formatting effects they represent are considered merely stylistic or
    otherwise out of scope for identifiers. To make matters worse, it's
    possible to misapply format characters such that users can create strings
    that look the same but actually contain different characters. For these
    reasons format characters are normally excluded from Unicode identifiers.
    The background document discusses a proposal to allow joiners in
    identifiers in certain contexts.
