NAME
Char - Multibyte Character Support by Traditional Scripting
SYNOPSIS
# encoding: sjis
use Char;
print "Hello, world wide market!\n";
# "no Char;" not supported
DESCRIPTION
The Char software provides multibyte character-oriented Perl environment
by traditional Perl scripting.
- Character oriented regular expression
- Character oriented runtime routines
- Character oriented subroutines
and
- Byte oriented CORE::* functions
- Byte oriented regular expression on /b modifier
Information processing model beginning with Perl3 or this software.

In UNIX Everything is a File
- In UNIX everything is a stream of bytes
- In UNIX the filesystem is used as a universal name space
Native Encoding Scripting
- native encoding of file contents
- native encoding of file name on filesystem
- native encoding of command line
- native encoding of environment variable
- native encoding of API
- native encoding of network packet
- native encoding of database
INSTALLATION
Just copy Char.pm to your @INC directory.
For example, to C:\Perl\site\lib on Microsoft Windows or other DOS-like
systems.

***************
Byte Oriented Character Oriented * Casual * Traditional
Functions vs Subroutines --> * Char Script * nearly Perl Script
------------- ---------------- *************** -----------
eval vs Char::eval --> * Char::eval * is not eval
length vs Char::length --> * length * is length
substr vs Char::substr --> * substr * is substr
ord vs Char::ord --> * ord * is ord
reverse vs Char::reverse --> * reverse * is reverse
getc vs Char::getc --> * getc * is getc
index vs Char::index --> * index * is index
rindex vs Char::rindex --> * rindex * is rindex
pos vs (nothing) --> * pos * is pos
m//b vs m// --> * m// * is m//
s///b vs s/// --> * s/// * is s///
split //b vs split // --> * split // * is split //
tr///b vs tr/// --> * tr/// * is tr///
qr//b vs qr// --> * qr// * is qr//
------------- ---------------- *************** -----------
- Data typing by switching operators, as traditional Perl style
- Text data by Character Oriented Subroutines
- Binary data by Byte Oriented Functions
- /b modifier was introduced via JPerl
- Multibyte Character Support by Traditional Scripting, in almost all cases
