       jfbterm - program to print several character sets on framebuffer device.


       jfbterm [options]


       This manual page documents briefly the jfbterm command.

       jfbterm  is  a program that prints various encodings such as UTF-8, ISO-8859-*, EUC-*, and
       so on, on Linux framebuffer device, like KON that  prints  on  VGA  device.   It  supports
       ISO-2022-compliant  character  sets,  encodings  which  consist  from such character sets,
       UTF-8, and encodings which iconv(3) can convert from/to UTF-8.  In GNU libc  systems,  all
       encodings which are available for iconv(3) meet this condition and are available.

       This  supports  fullwidth  characters  (which  occupies  two  columns,  like CJK Ideogram,
       Hiragana, Katakana, and Hangul).  However, this doesn't support combining  characters  nor


       This  program  follows  the usual GNU command line syntax, with long options starting with
       two dashes (`-').  A summary of options is included below.

       -h, --help
              Show summary of current configuration.

       -e, --exec, --shell
              Specify a program that run in jfbterm. Default is $SHELL  (or  /bin/sh).   Rest  of
              arguments will be passed to the specified program.

       -f, --config
              Specify a pathname of the configuration file. Default is /etc/jfbterm.conf.

       -c, --encoding, --charmap
              Specify the encoding.  The format is same as encoding line of jfbterm.conf(5) file.

              When  the  given  string  is "locale" (the first format), the encoding specified by
              LC_CTYPE locale is adopted.

              When the given string doesn't contain  `,'  (the  second  format),  the  string  is
              assumed  as  an  encoding  name.  A valid encoding name is either a name defined in
              encoding.encodingName line in jfbterm.conf(5) or a name which is valid for iconv(1)
              or iconv_open(3).

              When  the  given string contains a `,' (the third format), the string is assumed to
              have GL,GR,G0,G1,G2,G3 format.  See jfbterm.conf(5) for detail.

       -r, --reset
              Output ISO-2022 initialize sequence  to  tty.  You  can  specify  codeset  name  as
              optional argument like: --reset=encodingName.  Default is locale's codeset.

       -q, --quiet
              Don't print out messages.


       Since  version  0.3.14,  default  encoding  has  been  changed from EUC-JP to encoding for
       locale.  To make it enable to display EUC-JP, run

            $ jfbterm --reset=EUC-JP
            $ export LANG=ja_JP.eucJP
            $ jfbterm -r

       if you have already invoked jfbterm and are on it.  If you have not  invoked  jfbterm  and
       want to invoke it now, set LANG variable before invoking jfbterm.
