Description of problem: When choosing russian language and keyboard during Fedora installation, firstboot is using that keyboard layout as a default, and provides no way to input latin characters (toggle-layout key combination, which is pressing both shift keys, does not work either). This results in being unable to create a user, or do any other configuration which involves text input. I believe users from Greece, Ukraine or any country with cyrillic alphabet will have a similar problem.
