PICONV(1)				      Perl Programmers Reference Guide					   PICONV(1)

NAME
       piconv -- iconv(1), reinvented in perl

SYNOPSIS
	 piconv [-f from_encoding] [-t to_encoding]
		[-p|--perlqq|--htmlcref|--xmlcref] [-C N|-c] [-D] [-S scheme]
		[-s string|file...]
	 piconv -l
	 piconv -r encoding_alias
	 piconv -h

DESCRIPTION
       piconv is perl version of iconv, a character encoding converter widely available for various Unixen today.  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.

       piconv converts the character encoding of either STDIN or files specified in the argument and prints out to STDOUT.

       Here is the list of options.  Some options can be in short format (-f) or long (--from) one.

       -f,--from from_encoding
	   Specifies  the  encoding  you are converting from.  Unlike iconv, this option can be omitted.  In such cases, the
	   current locale is used.

       -t,--to to_encoding
	   Specifies the encoding you are converting to.  Unlike iconv, this option can be  omitted.   In  such	 cases,	 the
	   current locale is used.

	   Therefore, when both -f and -t are omitted, piconv just acts like cat.

       -s,--string string
	   uses string instead of file for the source of text.

       -l,--list
	   Lists  all  available encodings, one per line, in case-insensitive order.  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".	 See
	   Encode::Supported for a full discussion.

       -r,--resolve encoding_alias
	   Resolve encoding_alias to Encode canonical encoding name.

       -C,--check N
	   Check the validity of the stream if N = 1.  When N = -1, something interesting  happens  when  it  encounters  an
	   invalid character.

       -c  Same as "-C 1".

       -p,--perlqq
	   Transliterate characters missing in encoding to \x{HHHH} where HHHH is the hexadecimal Unicode code point.

       --htmlcref
	   Transliterate characters missing in encoding to &#NNN; where NNN is the decimal Unicode code point.

       --xmlcref
	   Transliterate characters missing in encoding to &#xHHHH; where HHHH is the hexadecimal Unicode code point.

       -h,--help
	   Show usage.

       -D,--debug
	   Invokes debugging mode.  Primarily for Encode hackers.

       -S,--scheme scheme
	   Selects which scheme is to be used for conversion.  Available schemes are as follows:

	   from_to
	       Uses Encode::from_to for conversion.  This is the default.

	   decode_encode
	       Input strings are decode()d then encode()d.  A straight two-step implementation.

	   perlio
	       The new perlIO layer is used.  NI-S' favorite.

	       You should use this option if you are using UTF-16 and others which linefeed is not $/.

	   Like the -D option, this is also for Encode hackers.
