TRCHAN(M)                                  UNIX System V



     Name
          trchan - translate character sets


     Syntax
          trchan [-ciko] mapfile


     Description
          trchan performs mapping as a filter, using the  same  format
          of  mapfile  as  mapchan(M) (described in mapchan(F)).
          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/*

     Notes
          trchan  currently  ignores  the  control  sections  of   the
          mapfile.


     Value Added
