I would actually suggest renaming the system user, if possible.

the "+" says that there's extended ACL present. So, nothing odd.

If you plan to mix Cygwin and system $HOME directories, make sure you mount
them with "noacl" flag in Cygwin.
Then permissions management will be deferred to Windows.

As any system administrator would tell you, user names with spaces, so is with
non-ASCII characters, are bad for system health.
