The <b>iconv</b> program converts text from one encoding to
another encoding. More precisely, it converts <b>from</b>
the encoding given for the <b>-f</b> option <b>to</b> the
encoding given for the <b>-t</b> option. Either of these
encodings defaults to the encoding of the current locale.
All the <i>inputfile</i>s are read and converted in turn; if
no <i>inputfile</i> is given, the standard input is used.
The converted text is printed to standard
output.</td></table>

The <b>iconv -l</b> or <b>iconv --list</b> command lists the
names of the supported encodings, in a system dependent
format. For the libiconv implementation, the names are
printed in upper case, separated by whitespace, and alias
names of an encoding are listed on the same line as the
encoding itself.</td></table>
