    Surely not. A combining character sequence consists of an optional base
    character followed by one or more combining characters. Canonical
    normalisation preserves the sequence of combining characters only,
    although it may reorder this sequence. It also preserves without
    reordering the juxtaposition of this seuqence to the optional base
    character. Therefore the combining character sequence is preserved.
