VT-IS-UTF8(1)                          Linux User's Manual                          VT-IS-UTF8(1)



NAME
       vt-is-UTF8 - check whether current VT is in UTF8- or byte-mode.


SYNOPSIS
       vt-is-UTF8 [-h|--help] [-V|--version] [-q|--quiet]


DESCRIPTION
       vt-is-UTF8  checks  whether the current VT is in UTF8 mode, by writing (and erasing after-
       wards) a 3-byte-long UTF8 sequence, and looking how much chars where displayed by the con-
       sole driver.

       A  message  telling  in which mode the console is is then written to stdout (except if the
       --quiet option was given).

       If the --quiet option is not given, the value returned is 1 if an error occurs, else 0.


OPTIONS
       -h --help
              display version number, a short help message and exit.


       -V --version
              display version number and exit.


       -q --quiet
              do not print on stdout in with mode we are, but return the state as  exit-status  1
              if  in  UTF8-mode, 0 if in byte-mode. In case of error, 0 is returned and a message
              is displayed on stderr.


BUGS
       The check should be done by directly asking the kernel, which is not possible as  of  ker-
       nels 2.0.x.

       As  of  kernel 2.0.35, the byte-mode is sometimes erroneously detected as UTF8-mode, after
       switching from a 512-chars font to a 256-chars font.  This is  probably  a  console-driver
       bug.
