Folders via IMAP not working with German umlauts or ampersand in folder name

[dfied]

Client: current Thunderbird version 128.5.0
Gromox: gromox-2.38.5.g9866cfd-6.1
Rocky Linux 9.5 with current updates

Since some days I have problems using folders in gromox-imap that have german umlauts in its folder names. Also folders with ampersand are affected.
I thought this was caused by #114 but the fix only stopped the sqlite error in the midb logs but the folders are still not accessible. The folders are greyed out in Thunderbird. When opening the subscribe dialog for folders, those folder are shown twice.
Also affected are the Trash folder (Gelöschte Objekte in German) and Drafts (Entwürfe).
Grommunio Web and Grommunio Sync are working as expected.

How can I help to analyze this problem?

bye
Daniel

Also tested with other folders than trash. Claws-Mail here.

And i also can now see i can't access the trash in the shared mailbox which is german (i always set mine to english..)

PS: gromox-2.38.0.8963230-lp156.4.1.x86_64 and gromox-2.38.10.22eab48-lp156.7.1.x86_64 the same..

I just ran "search for new folders" on every mailbox and this fixed as it seems the usage of "Gelöschte Objekte" as i now can use the "emtpty" function.
Odd thing is that one of the mailboxes appears to be now english even tho it is displayed with de_DE in exmdb store get and another mailbox is shown as german like it used to.
Furthermore i can't seem to create/delete any folder with claws-mail. With alpine it worked tho .. 🙈

claws does not know RFC 6154, and always (re-)creates folders called Trash, Drafts, Queue even if you already have Gelöschte Elemente, Entwürfe, etc.

yeah, but i also have the same english view in the webapp so that wasn't only in claws :P.
