    There are several meanings of "compatibility characters".

    The most important here are the characters that have a
    compatibility decomposition mapping. For details,
    see UTR 20:

    The oe ligature characters have no decomposition at all.

    Which is unrelated to the question posed! See UTR 20 instead.
