jfbterm - program to print several character sets on framebuffer
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

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