In fresh installation of freebsd 13 from iso FreeBSD-13.0-RELEASE-amd64-dvd1.iso french keyboard with french accentuations selected, on javaconsole (remote console), when in installer form to type characters to test, each type an accent is typed, a untimely tabulation is inserted so you cannot type many characters.
Thank you for the report, This is a known problem, this PR duplicates bug #248968 (and bug #257338). It is just a "graphical" problem during the installation keymap test, it is not related to the OS keyboard setting, after the installation reboot you'll have keymap="fr.iso" in /etc/rc.conf. You can know more or test the solution (after installation) described in bug #248968. I hope to commit soon the patch to update/fix the installer. Alfonso
