Hi @ertank,
may I ask you which is the nationality of your name?
IMVHO should be not user-workable this issue, but, maybe Dev Team may report to Cockpit Project.
Or the “default config” of Cockpit should be changed…
It is only removed from non-ascii characters on top right corner.
BTW, I failed to login using a regular user (just the above one I created for test purposes). I see below in /var/log/messages

I can login just fine using root user.
Just for the record, I am behind a Squid Proxy server if that makes any difference.
for the timeout, check the user has a shell access (advanced menu of the user), you have a checkbox
Relative to UTF8 caracters, we have no validators for the gecos (Name), therefore you are not limited to use what you want but maybe cockpit does not use it well
in /usr/libexec/nethserver/api/system-users/validate:
