This answer presupposes that there is a well-defined concept of which
base character a combining mark belongs to. That is not always true. The
particukar combining mark which precipitated the debate may be situated
above the gap between the (logically and phonetically) preceding and
following characters, or may move on to the preceding or the following
characters depending on the precise context and on the typographer's
Anyway, John J, what code are we talking about that has to work from the
positions of the combining marks back to the underlying representation?
Are you talking about OCR?
