The setting of SOGoSieveFolderEncoding must match your dovecot setting
in mail_location.
Default in Dovecot is mUTF-7-encoding
If there is a ":UTF-8" in mail_location, then you have UTF-8-encoding in

If changed in SOGo on an already productive server, you have to change
the encoding of all folders created with SOGo and non-ASCII characters
to UTF-8 with:
doveadm mailbox mutf7 -7 ${WRONG_FOLDER_NAME}
Best to do that in a script ;-)
