selected keyboard layout does not immediately take effect on the tty

After selecting the keyboard layout and finishing the wizard, one is presented with tuigreet on the current tty. But that tty will not yet use the selected keyboard layout and thus it becomes a potential problem to enter the username and especially the password (which might contain special characters). Maybe there is a way to immediately let the changes to /etc/default/keyboard take effect on all ttys?

EDIT: running the following command makes changes to /etc/default/keyboard take effect on the ttys: setupcon --force
