If set to the value yes, this keyword indicates that the
system default locale is one that needs support for multibyte
characters.
In this case, the
loadfont(1M)
command will initiate
multibyte console mode when it is called, and the system will
initiate multibyte console mode on reboot.
If unset or set to any value other than yes, the system
default locale is one that does not need support for multibyte
characters.
