    Dear list members,
    especially those favouring the encoding of emoji.

    Please address the inquiry below (already posted earlier, but unduly ignored):

    In my understanding glyph variations (latin ligatures, arabic
    contextual alternates) are ever only encoded to solve round tripping
    with _preexisting_ standards.
