    Unicode 5.0 addresses this directly on page 500, where it says:

    Occasionally one runs across orthographic conventions that use a dot, an
    acute accent, or
    other simple diacritic above a ligature tie?that is, U+0361 combining
    double inverted
    breve. Because of the considerations of canonical order just discussed,
    one cannot represent
    such text simply by putting a combining dot above or combining acute
    directly after
    U+0361 in the text. Instead, the recommended way of representing such text
    is to place
    U+034F combining grapheme joiner (CGJ) between the ligature tie and the
    mark that follows it, as shown in Figure 7-10.

    Because this is a relatively recent Unicode ruling, there are not yet many
    fonts that will render this sequence correctly. but there is no question
    that this is the correct encoding.
