NAME
Char - Character Oriented Perl by Magic Comment
SYNOPSIS
# encoding: sjis
use Char;
print "Hello, world wide market!\n";
# "no Char;" not supported
DESCRIPTION
The Char software provides character oriented Perl scripting
environment by easy installation and easy usage.
- 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.

| Basically, |
| Text strings as Binary strings |
| Binary strings as Text strings |
+--------------------------------------------+
| Not UTF8 Flagged, UNIX/C-ism |
+--------------------------------------------+
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 on Operating Systems
- same as Content of a file
- same as Filename on the filesystem
- same as Command line
- same as Environment variable
- same as Parameter of API
INSTALLATION
Just copy Char.pm to your @INC directory.
For example, to C:\Perl\site\lib
