NAME
Latin2 - Native Encoding Support by Traditional Scripting
SYNOPSIS
# encoding: Latin2
use Latin2;
print "Hello, world wide market!\n";
# "no Latin2;" not supported
DESCRIPTION
The Latin2 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 Latin2::* subroutines
and
- Byte oriented CORE::* built-in functions
- Byte oriented regular expression on /b modifier
Information processing model beginning with Perl3 or this software.

| Not UTF8 Flagged, No Mojibake |

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.
(I don't say what are not;)
Byte Oriented Character Oriented
Functions vs Subroutines
------------- ----------------
eval vs Latin2::eval
length vs Latin2::length
substr vs Latin2::substr
ord vs Latin2::ord
reverse vs Latin2::reverse
getc vs Latin2::getc
index vs Latin2::index
rindex vs Latin2::rindex
pos vs (nothing)
m//b vs m//
s///b vs s///
split //b vs split //
tr///b vs tr///
qr//b vs qr//

****************
* Casual * Traditional
* Scripting * nearly Perl Script
**************** -----------
* Latin2::eval * is not eval
* length * is length
* substr * is substr
* ord * is ord
* reverse * is reverse
* getc * is getc
* index * is index
* rindex * is rindex
* pos * is pos
* m// * is m//
* s/// * is s///
* split // * is split //
* tr/// * is tr///
* qr// * is qr//
**************** -----------
- 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
