Bug: Creation of Group with non-latin characters not possible

[frankmayer]

Steps to reproduce

1. Go into Contacts
2. Click "+New group"
3. In the text field enter anything non-latin (I entered "Δοκιμή" which is greek for "Test") Attention: The group will display in the list, but will not actually be created in the backend until a contact is added to it.
4. Try to add a contact to this list. It will fail, displaying "Adding 0 contacts to Δοκιμή"... and Browser log (console) throws the message I have included below

Expected behaviour

Group is created, contact is added

Actual behaviour

Fails to create group and add a contact

[catkic]

I have the same problem

[frankmayer]

This issue https://github.com/nextcloud/deck/issues/2780 is probably having the same underlying problem.

Tested. This is now working.
