Hi Paul

Thank you for the suggestion.
I have tried with:

- name: SV-Oevrige_objekter
    title: SV-Oevrige objekter
    sources: ['wms_trans:\u00D8vrige_objekter']

and

- name: SV-Oevrige_objekter
    title: SV-Oevrige objekter
    sources: ['wms_trans:\xD8vrige_objekter']

In both circumstances, the escape is not interpreted so the request sent to the remote WMS is:
wms?layers=%5Cu00D8vrige_objekter&styles=
