trchan(1)                        UNIX System V                        trchan(1)


NAME
      trchan - translate character sets

SYNOPSIS
      trchan [-ciko] mapfile

DESCRIPTION
      trchan performs mapping as a filter, using the same format of mapfile as
      mapchan [see mapchan(4) for mapfile format].  This allows a file
      consisting of one internal character set to be translated to another
      internal character set.

      trchan reads standard input, maps it, and writes to standard output.  A
      mapfile must be given on the command line.  Errors cause trchan to stop
      processing unless -c is specified.

      The following options can be used with trchan:

      -c    causes errors to be echoed on stderr, and processing is continued.

      -i    specifies that the input section of the mapfile is used when
            translating data.

      -k    specifies that the dead and compose sections of the mapfile are
            used when translating data.

      -o    specifies that the output section of the mapfile is used when
            translating data.

            The -i, -k and -o options can be specified in any combination; if
            none are specified, trchan uses the entire mapfile, as if all three
            were specified together.

FILES
      /usr/lib/mapchan/*

SEE ALSO
      ascii(5), mapchan(4), mapchan(1M)

NOTES
      trchan currently ignores the control sections of the mapfile.
