.TH TCS 1
.SH NAME
tcs \- translate character sets
.SH SYNOPSIS
.B tcs
[
.B -slcv
]
[
.B -f
.I ics
]
[
.B -t
.I ocs
]
[
.I file ...
]
.SH DESCRIPTION
.I Tcs
interprets the named
.I file(s)
(standard input default) as a stream of characters from the
.I ics
character set or format, converts them to runes,
and then converts them into a stream of characters from the
.I ocs
character set or format on the standard output.
The default value for
.I ics
and
.I ocs
is
.BR utf ,
the
.SM UTF
encoding described in
.IR utf (6).
The
.B -l
option lists the character sets known to
.IR tcs .
Processing continues in the face of conversion errors (the
.B -s
option prevents reporting of these errors).
The
.B -c
option forces the output to contain only correctly converted characters;
otherwise,
.B 0x80
characters will be substituted for
.SM UTF
encoding errors and
.B 0xFFFD
characters will substituted for unknown characters.
.PP
The
.B -v
option generates various diagnostic and summary information on standard error,
or makes the
.B -l
output more verbose.
