− put keyboard and console in unicode mode
unicode_start command will put the keyboard and
console into Unicode (UTF-8) mode.
keyboard this means that one can attach 16-bit U+xxxx values
to keyboard keys using loadkeys(1), and have these
appear as UTF-8 input to user programs. Also, that one can
type hexadecimal Alt-xxxx using the numeric keypad, and
again produce UTF-8.
For the console
this means that the kernel expects UTF-8 output from user
programs, and displays the output accordingly.
font is a font that is loaded. It should have a
built-in Unicode map, or, if it hasn’t, such a map can
be given explicitly as second parameter. When no font was
specified, the current font is kept.
Unicode mode is
a parameter with a value per virtual console. However,
usually the font and keymap is common to all consoles.
