luit - Locale and ISO 2022 support for Unicode terminals
luit [ options ] [ -- ] [ program [ args ] ]
Luit is a filter that can be run between an arbitrary application and a UTF-8 terminal
emulator. It will convert application output from the locale's encoding into UTF-8, and
convert terminal input from UTF-8 into the locale's encoding.
An application may also request switching to a different output encoding using ISO 2022
and ISO 6429 escape sequences. Use of this feature is discouraged: multilingual
applications should be modified to directly generate UTF-8 instead.
Luit is usually invoked transparently by the terminal emulator. For information about
running luit from the command line, see EXAMPLES below.
-h Display some summary help and quit.
-list List the supported charsets and encodings, then quit.
-V Print luit's version and quit.
-v Be verbose.
-c Function as a simple converter from standard input to standard output.
-p In startup, establish a handshake between parent and child processes. This is
needed for some systems, e.g., FreeBSD.
-x Exit as soon as the child dies. This may cause luit to lose data at the end of the
Set the child's name (as passed in argv).
Set up luit to use encoding rather than the current locale's encoding.
+oss Disable interpretation of single shifts in application output.
+ols Disable interpretation of locking shifts in application output.
+osl Disable interpretation of character set selection sequences in application output.
+ot Disable interpretation of all sequences and pass all sequences in application
output to the terminal unchanged. This may lead to interesting results.
-k7 Generate seven-bit characters for keyboard input.
+kss Disable generation of single-shifts for keyboard input.
+kssgr Use GL codes after a single shift for keyboard input. By default, GR codes are
generated after a single shift when generating eight-bit keyboard input.
-kls Generate locking shifts (SO/SI) for keyboard input.
-gl gn Set the initial assignment of GL. The argument should be one of g0, g1, g2 or g3.
The default depends on the locale, but is usually g0.
-gr gk Set the initial assignment of GR. The default depends on the locale, and is
usually g2 except for EUC locales, where it is g1.
Set the charset initially selected in G0. The default depends on the locale, but
is usually ASCII.
Set the charset initially selected in G1. The default depends on the locale.
Set the charset initially selected in G2. The default depends on the locale.
Set the charset initially selected in G3. The default depends on the locale.
Log into filename all the bytes received from the child.
Log into filename all the bytes sent to the terminal emulator.

-- End of options.
The most typical use of luit is to adapt an instance of XTerm to the locale's encoding.
Current versions of XTerm invoke luit automatically when it is needed. If you are using
an older release of XTerm, or a different terminal emulator, you may invoke luit manually:
$ xterm -u8 -e luit
If you are running in a UTF-8 locale but need to access a remote machine that doesn't
support UTF-8, luit can adapt the remote output to your terminal:
$ LC_ALL=fr_FR luit ssh legacy-machine
Luit is also useful with applications that hard-wire an encoding that is different from
the one normally used on the system or want to use legacy escape sequences for
multilingual output. In particular, versions of Emacs that do not speak UTF-8 well can
use luit for multilingual output:
$ luit -encoding 'ISO 8859-1' emacs -nw
And then, in Emacs,
M-x set-terminal-coding-system RET iso-2022-8bit-ss2 RET
