NAME

 Char - Native Encoding Support by Traditional Scripting

SYNOPSIS

 # encoding: sjis
 use Char;
 print "Hello, world wide market!\n";

 # "no Char;" not supported

DESCRIPTION

 The Char software provides character-oriented Perl environment on the
 native encoding, by traditional scripting that we know.

 - Character oriented regular expression and runtime routines
 - Character oriented Char::* subroutines
     and
 - Byte oriented CORE::* built-in 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

SUBROUTINES

 Old Days -- memories are always beautiful.

   Functions of
   Byte and SBCS -- Traditional Perl Script
   -------------
   eval
   length
   substr
   ord
   reverse
   getc
   index
   rindex
   pos
   m//
   s///
   split //
   tr///
   qr//

 Today -- some memories are beautiful, others are not.

 - Data typing by switching operators, like 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
