Forget about mUTF-7 with Dovecot. It's an IMAP-protocol relic, and Dovecot is
trying to get rid of it in as many places as possible. Although by default the
filesystem users mUTF-7, but that can also be changed with a setting.

I suspect your shell is breaking the 8bit chars into invalid UTF-8. I just
tried and it works fine with me.

Folders aren't indexed by default (mailbox_list_index=no) and force-resync
doesn't affect them. Are you saying "doveadm mailbox list -u user" doesn't show
some folder? I'm not aware of any bugs related to this.

I'd need to get some more specifics. Show show exists in filesystems and what
commands don't produce expected results (and what they produce instead).

Nah, mUTF-7 hopefully will die some day.
