Odoo 13 docker redirect breaks urls containing utf-8 scandinavian chars

[aleskinen]

If in container I do: root@odoo13dev-stateful-0:/# curl -i localhost:8069/en_GB/sp_integration/dir/t%C3%A4t%C3%A4%20testataan%20%C3%B6%C3%B6 HTTP/1.0 302 FOUND Content-Type: text/html; charset=utf-8 Content-Length: 455 Location: http://localhost:8069/web/login?redirect=http%3A%2F%2Flocalhost%3A8069%2Fsp_integration%2Fdir%2Ft%EF%BF%BDt%EF%BF%BD+testataan+%EF%BF%BD%EF%BF%BD As you see there is no character %C3%A4 (ä) in redirect url and this url does not work. Is there something wrong in configuration of odoo or linux. Any ideas how to resolve problem? I am using quite resent odoo13 docker image as base image.

Thank you of any help.
