NAME
       luit - Locale and ISO 2022 support for Unicode terminals

SYNOPSIS
       luit [ options ] [ -- ] [ program [ args ] ]

DESCRIPTION
       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	encod‐
       ing  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.

OPTIONS
       -h     Display some summary help and quit.

       -list  List the supported charsets and encodings, then quit.

       -v     Be verbose.

       -c     Function	as  a simple converter from standard input to standard
	      output.

       -x     Exit as soon as the child dies.  This may	 cause	luit  to  lose
	      data at the end of the child's output.

       -argv0 name
	      Set the child's name (as passed in argv[0]).

       -encoding encoding
	      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 gener‐
	      ating 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.

       -g0 charset
	      Set  the	charset initially selected in G0.  The default depends
	      on the locale, but is usually ASCII.

       -g1 charset
	      Set the charset initially selected in G1.	 The  default  depends
	      on the locale.

       -g2 charset
	      Set  the	charset initially selected in G2.  The default depends
	      on the locale.

       -g3 charset
	      Set the charset initially selected in G3.	 The  default  depends
	      on the locale.

       -ilog filename
	      Log into filename all the bytes received from the child.

       -olog filename
	      Log into filename all the bytes sent to the terminal emulator.

       --     End of options.

EXAMPLES
       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,  ver‐
       sions  of Emacs that do not speak UTF-8 well can use luit for multilin‐
       gual output:

	      $ luit -encoding 'ISO 8859-1' emacs -nw

       And then, in Emacs,

	      M-x set-terminal-coding-system RET iso-2022-8bit-ss2 RET

FILES
       /usr/X11R6/lib/X11/fonts/encodings/encodings.dir
	      The system-wide encodings directory.

       /usr/X11R6/share/X11/locale/locale.alias
	      The file mapping locales to locale encodings.

SECURITY
       On systems with SVR4 (``Unix-98'') ptys (Linux version 2.2  and	later,
       SVR4), luit should be run as the invoking user.

       On systems without SVR4 (``Unix-98'') ptys (notably BSD variants), run‐
       ning luit as an ordinary user will leave the tty	 world-writable;  this
       is  a security hole, and luit will generate a warning (but still accept
       to run).	 A possible solution is to make luit suid  root;  luit	should
       drop  privileges	 sufficiently  early  to make this safe.  However, the
       startup code has not been exhaustively audited, and the author takes no
       responsibility for any resulting security issues.

       Luit  will  refuse  to  run if it is installed setuid and cannot safely
       drop privileges.

BUGS
       None of this complexity should be necessary.  Stateless UTF-8  through‐
       out the system is the way to go.

       Charsets with a non-trivial intermediary byte are not yet supported.

       Selecting  alternate  sets  of  control characters is not supported and
       will never be.
