.SH NAME
jfbterm \- program to print several character sets on framebuffer device.
.SH SYNOPSIS
.B jfbterm
.RI [ options ]
.\" =======================================================================
.SH DESCRIPTION
This manual page documents briefly the
.B jfbterm
command.
.PP
\fBjfbterm\fP 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 \fBiconv\fR(3) can convert from/to UTF\-8.
In GNU libc systems, all encodings which are available for \fBiconv\fR(3)
meet this condition and are available.
.PP
This supports fullwidth characters (which occupies two columns, like
CJK Ideogram, Hiragana, Katakana, and Hangul). However, this doesn't
support combining characters nor BIDI.
.\" =======================================================================
.SH OPTIONS
This program follows the usual GNU command line syntax, with long
options starting with two dashes (`\-').
A summary of options is included below.
.TP
.B \-h, \-\-help
Show summary of current configuration.
.TP
.B \-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.
.TP
.B \-f, \-\-config
Specify a pathname of the configuration file. Default is /etc/jfbterm.conf.
.TP
.B \-c, \-\-encoding, \-\-charmap
Specify the encoding. The format is same as \fBencoding\fR line
of \fBjfbterm.conf\fR(5) file.
.IP
When the given string is "locale" (the first format), the encoding
specified by LC_CTYPE locale is adopted.
.IP
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.\fIencodingName\fR line in \fBjfbterm.conf\fR(5)
or a name which is valid for \fBiconv\fR(1) or \fBiconv_open\fR(3).
.IP
When the given string contains a `,' (the third format), the
string is assumed to have
\fIGL\fR,\fIGR\fR,\fIG0\fR,\fIG1\fR,\fIG2\fR,\fIG3\fR format.
See \fBjfbterm.conf\fR(5) for detail.
.TP
.B \-r, \-\-reset
Output ISO\-2022 initialize sequence to tty. You can specify codeset name
as optional argument like: \fB\-\-reset=\fP\fIencodingName\fP.
Default is locale's codeset.
.TP
.B \-q, \-\-quiet
Don't print out messages.
.\" =======================================================================
.SH 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
.nf
$ jfbterm \-\-reset=EUC\-JP
or
$ export LANG=ja_JP.eucJP
$ jfbterm \-r
.fi
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.
