<p style="margin-left:11%; margin-top: 1em">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.</p>
