I’m under Mojave and I don’t have the issue, but some users under Catalina reported me problem which seem to be problem with Accentuated characters.
I’ve filled a bug report #60309 but as there isn’t answer, I would to know if I’m the only one to have the problem with its applications.
I sync 2 folders, FolderA and FolderB.
(my Method is more complicated but to explain the problem I do it simplest).
I first loop inside the two folders and I have two arrays with the name of the items contained by each folder, ArrayFoldA and ArrayFoldB .
Then, I loop each item of ArrayFoldA and I do ArrayFoldB.IndexOf(ArrayFoldA(ThisIndex)).
If result is -1 it is suppose to not be present in FolderB then I copy it. First, I do a check to verify it is ok and it is not, it exists as FolderB.Child(ArrayFoldyA(ThisIndex)).exists return True
It happens with accentuated characters like “Clia Mara”. It seems it depend of the way the is encoded. With the key key (then only one digit) or with the key and then with the key e to obtain (2 digits).
