Research direction

The report names the Nextcloud Talk for Android login flow but no source files or tests. Reproduce the failure with a username such as "jöhn.doe" and trace the login entry points on the Android and server sides. Done means users with special characters in their usernames can log in without the app claiming Talk is not installed.
