56<p style="margin-left:11%; margin-top: 1em">The
57<b>iconv</b> program converts text from one encoding to
58another encoding. More precisely, it converts <b>from</b>
59the encoding given for the <b>&minus;f</b> option <b>to</b>
60the encoding given for the <b>&minus;t</b> option. Either of
61these encodings defaults to the encoding of the current
62locale. All the <i>inputfile</i>s are read and converted in
63turn; if no <i>inputfile</i> is given, the standard input is
64used. The converted text is printed to standard output.</p>
65
66<p style="margin-left:11%; margin-top: 1em">The encodings
67permitted are system dependent. For the libiconv
68implementation, they are listed in the iconv_open(3) manual
69page.</p>
