tcs - translate character sets

Tcs  interprets  the  named  file(s)  (standard  input  default)  as  a stream of characters from the ics
       character set or format, converts them to runes, and then converts them into a stream of characters  from
       the  ocs  character  set or format on the standard output.  The default value for ics and ocs is utf, the
       UTF encoding described in utf(6).  The -l option lists the  character  sets  known  to  tcs.   Processing
       continues  in  the  face of conversion errors (the -s option prevents reporting of these errors).  The -c
       option forces the output to contain only correctly converted characters; otherwise, 0x80 characters  will
       be substituted for UTF encoding errors and 0xFFFD characters will substituted for unknown characters.

       The  -v  option  generates  various diagnostic and summary information on standard error, or makes the -l
       output more verbose.

       Tcs recognizes an ever changing list of character sets.  In particular, it supports a variety of  Russian
       and Japanese encodings.  Some of the supported encodings are
