There is the same issue with liturgical latin where a e i o u y æ œ can
take an acute without changing their meaning at all. Maybe i and u could
be treated in a slightly different way with patterns because when they
take acute they cannot be consonnants, which changes the hyphenation;
but for the other letters, an equivalent class would reduce the number
of patterns.

I agree that "œ+combining acute" should be treated the same as œ, but
should it count as 1 or two characters (o+e) for the
right/left/hyphenmin? I'm not sure about that, but maybe some would
treat it as two characters....

Is there a place where these problems/issues are tracked? the TODO file
of the repository is quite messy...

Thank you,
