From d305a67b46644d6360ef557109384c831ee8e018 Mon Sep 17 00:00:00 2001

Subject: [PATCH] vconsole-setup: enable utf-8 mode explicitly
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
Rather than assuming the console is in utf-8 mode if nothing else is
specified, be a bit more robust and enable it explicitly.
This fixes a regression compared with Arch's initscripts when not
using a framebuffer as the old VGA console would not be in utf-8
mode by default.
Furthermore, this would allow vconsole-setup to be used after boot
to change the vconsole into utf-8 mode in case it has been set to
non-utf-8 mode for whatever reason. I.e, the following would leave
the console in utf-8 mode as expected:
# export LANG=en_US.ISO-8859-1
# /usr/lib/systemd/systemd-vconsole-setup
# export LANG=en_US.UTF-8
# /usr/lib/systemd/systemd-vconsole-setup
