NAME Latin4 - Native Encoding Support by Traditional Scripting SYNOPSIS # encoding: Latin4 use Latin4; print "Hello, world wide market!\n"; # "no Latin4;" not supported DESCRIPTION The Latin4 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 Latin4::* subroutines and - Byte oriented CORE::* built-in functions - Byte oriented regular expression on /b modifier Information processing model beginning with Perl3 or this software. +--------------------------------------------+ | Text string as Digital octet string | | Digital octet string as Text string | +--------------------------------------------+ | 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.
