NAME
charset - Set an ACM for use in one of the G0/G1 charset slots.
SYNOPSIS
I charset [ -v ] G0 | G1 [ cp437 | iso01 | vt100 | user | <acm_name> ]
DESCRIPTION
The linux console has 2 slots for charsets, labeled
G0
and
R G1 .
charset
changes the slot in use by the current VT to either
G0
or
R G1 ,
and fills the slot either with one of the 3 predefined ACMs
(cp437, iso01, vt100)
or with a user-defined ACM.
You can ask for the current user-defined ACM by specifying
R user ,
or ask a new ACM to be loaded from a file into the user slot, by
specifying a filename.
You will note that, although each VT has its own slot settings, there
is only one user-defined ACM for all the VTs. That is, whereas you
can have tty1 using
G0=cp437
and
R G1=vt100 ,
at the same time as tty2 using
G0=iso01
and
G1=iso02
(user-defined), you
cannot
have at the same time tty1 using
iso02
and tty2 using
R iso03 .
This is a limitation of the linux kernel.
Note that you can emulate such a setting using the
filterm(1)
utility, with your console in UTF8-mode, by telling
filterm
to translate screen output on-the-fly to UTF8.
You'll find
filterm(1)
in the
konwert(1)
package, by Marcin Kowalczyk, which is available from
R http://qrczak.home.ml.org/ .
OPTIONS
-v
be verbose.
charset
will then print what it does as it does it.
BUGS
charset
cannot determine which of the 2 slots is in use at a given time, so
you have to tell him which one you want, even if you don't want to
change to the other one. This is a limitation of the console driver.
