This script was primarily a technology demonstrator for Perl 5.8.0, but you can use piconv in the place of iconv for virtually any case.</p> <p>piconv converts the character encoding of either STDIN or files specified in the argument and prints out to STDOUT.</p> <p>Here is the list of options. Each option can be in short format (-f) or long (--from).</p> <dl> <dt id="-f,-from-from_encoding"><a class="permalink" href="#-f,-from-from_encoding">#</a><a id="f---from-from_encoding"></a>-f,--from from_encoding</dt> <dd> <p>Specifies the encoding you are converting from.

Note that only the canonical names are listed; many aliases exist. For example, the names are case-insensitive, and many standard and common aliases work, such as "latin1" for "ISO-8859-1", or "ibm850" instead of "cp850", or "winlatin1" for "cp1252".
