After selecting non-Latin keyboard layouts in the graphical installer, there is no way to input Latin characters again. This means hostname, username, password, the home directory path /home/… cannot be specified in Latin.
There either should be a way to switch the keyboard layout later on. For example currently there is neither a place in the GUI to switch the layout nor key combinations or (on a Japanese keyboard) support for the keyboard’s romaji key to switch layouts. Of course typing `loadkeys` is impossible too. Or the keyboard layout should not be switched to non-Latin. For example, when choosing Arabic AZERTY layout, during install the keyboard should be switched to Latin AZERTY layout and not Arabic. Note that choosing non-Latin usernames and passwords appears to have caused problems before, see <https://bugs.gnu.org/37872> (I have not tested it). Similar considerations: Maybe the default keyboard layout for virtual console TTYs and bootloaders should be Latin unless changed explicitly. Regards, Florian
