    Then Hebrew-language users are going to have great difficulty in typing
    URLs containing IDNs that contain GERESH or GERSHAYIM, unless either
    their input method can translate the characters automatically, or their
    user-agents have special language-context-sensitive URL parsing code
    which allows the apostrophe and double-quote characters in the context
    of Hebrew letters, and then converts them to the correct characters in
    the IDN. The latter is unlikely, as it will break numerous RFCs.

    Are there unambiguous transformation rules that could be used to
    transform input using the substitute characters to output using the
    correct characters, or will there always be an ambiguity with other uses
    of these characters?
