trchan(M)

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.

Limitations

trchan currently ignores the control sections of the mapfile.
