NAME    [Toc]    [Back]

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

SYNOPSIS    [Toc]    [Back]

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

DESCRIPTION    [Toc]    [Back]

       vt-is-UTF8  checks  whether  the current VT is in UTF8 mode, by writing
       (and erasing afterwards) a 3-byte-long UTF8 sequence, and  looking  how
       much chars where displayed by the console 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    [Toc]    [Back]

       -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    [Toc]    [Back]

       The  check  should  be done by directly asking the kernel, which is not
       possible as of kernels 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.
