 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 char-
    acter 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.

 File

 Note

    trchan currently ignores the control sections of the mapfile.
