I think the main point is that it is not treated the same way as œ. For
instance with right/lefthyphenmin = 2, we have

œ́-di-pus
œdi-pus

while they should be the same...

If I understand correctly, you're saying that in order to have œ treated
as 2 characters (with lefthyphenmin=2), I should have lefthyphenmin=1
and completely redo the patterns so that all the sequences of two
characters at the beginning of a word do not get separated... If I
understood correctly, that just looks terrible...

Thank you,
