JFBTERM(1)

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

SYNOPSIS
jfbterm [options]

DESCRIPTION
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 BIDI.

OPTIONS
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).

-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.

NOTES
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
or
	$ 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.
