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 BIDI.

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 code Äê

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.
