Problem with diacritics

[Dejieres]

Hello,

I'm trying to save some mailboxes, but stumbled over a problem with an IMAP account that was accessed with the french version of Outlook. Outlook creates folders with accented characters, like Éléments envoyés, which prevent correct access to the folder :

Calling getmail to retrieve mail for mailbox "/home/-----/IMAPbackup/adrtest//INBOX.&AMk-l&AOk-ments envoy&AOk-s" Downloading mailbox "INBOX.&AMk-l&AOk-ments envoy&AOk-s" getmail version 6.14 Copyright (C) 1998-2020 Charles Cazabon and others. Licensed under GNU GPL version 2. SimpleIMAPRetriever:[email protected]@mail.-----.com:143: mailbox b'INBOX.&AMk-l&AOk-ments envoy&AOk-s' not selectable (INBOX.&AMk-l&AOk-ments envoy&AOk-s) - verify the mailbox exists and you have sufficient permissions 0 messages (0 bytes) retrieved, 0 skipped

Is there anything I can try to get it working (I don't know Python) ?

Running on Debian 11, Python 2.7.18
