Resetting the console, either by ANSI escape sequences or by the reset utility,
will drop the console back to legacy (non-UTF-8) mode. Fix this by leaving the
field vc_data.vc_utf untouched in reset_terminal(). In addition, a global
variable (default_utf8) which defines system-wide UTF-8 setting is created.
This variable can be adjusted via sysfs.
This is based from patches by Jan Engelhardt and Paul LeoNerd Evans.
