--- Comment #2 from Garrett D'Amore <garr...@damore.org> ---
This problem is not limited to ZWJ:

For example:

    s2 = "\U0001F44D\U0001F3fD";
    writefln("s2 is %s\n", s2);
    writefln("graphemes %d (expect 1)\n", wr.walkLength); // this should be "1"

That is a thumbs up with a skin tone modifier.  That should be one grapheme.
