NAME

       Char::USASCII - Source code filter for US-ASCII script (Imitation JPerl)

SYNOPSIS

    In your script:

      use Char::USASCII; # CPAN formal style
         or
      use USASCII; # casual style

    At command prompt:

      perl  yourscript.pl  wild*  *card  and  '*quote*'  on MSWin32

DESCRIPTION

      This software is "JPerl on the Modern Perl" written by Perl.
      This software treats US-ASCII directly. Therefore, there is not UTF8 flag.

INSTALLATION BY MAKE (for UNIX like system)

To install this software by make, type the following:

   perl Makefile.PL
   make
   make test
   make install

   Rename and install strict.pm_ of this distribution to strict.pm if your system
   doesn't have strict.pm.

INSTALLATION WITHOUT MAKE (for DOS like system)

To install this software without make, type the following:

   perl pMakefile.PL    --- pMakefile.PL makes "pmake.bat" only, and ...
   pmake.bat
   pmake.bat test

   pmake.bat install    --- install to current using Perl

   Rename and install strict.pm_ of this distribution to strict.pm if your system
   doesn't have strict.pm.

   pmake.bat dist       --- make distribution package
   pmake.bat ptar.bat   --- make perl script "ptar.bat"

DEPENDENCIES

This software requires perl5.00503 or later.

This article is about the character encoding. For other uses, see ASCII
(disambiguation).

All 128 ASCII characters including non-printable characters (represented by
their abbreviation).
 The 95 ASCII graphic characters are numbered from 0x20 to 0x7E (32 to 126
decimal). The space character is considered a non-printing graphic.

The American Standard Code for Information Interchange (ASCII, ass-kee) is a
character-encoding scheme based on the ordering of the English alphabet.
ASCII codes represent text in computers, communications equipment, and other
devices that use text. Most modern character-encoding schemes are based on
ASCII, though they support many more characters than ASCII does.

US-ASCII is the Internet Assigned Numbers Authority (IANA) preferred charset
name for ASCII.

Historically, ASCII developed from telegraphic codes. Its first commercial use
was as a seven-bit teleprinter code promoted by Bell data services. Work on
ASCII formally began on October 6, 1960, with the first meeting of the
American Standards Association's (ASA) X3.2 subcommittee. The first edition of
the standard was published during 1963, a major revision during 1967, and the
most recent update during 1986. Compared to earlier telegraph codes, the
proposed Bell code and ASCII were both ordered for more convenient sorting
(i.e., alphabetization) of lists, and added features for devices other than
teleprinters.

ASCII includes definitions for 128 characters: 33 are non-printing control
characters (now mostly obsolete) that affect how text and space is processed;
94 are printable characters, and the space is considered an invisible graphic.
The most commonly used character encoding on the World Wide Web was US-ASCII
until December 2007, when it was surpassed by UTF-8.


* ALGORITHM #1

 When the character is taken out of the octet string, it is necessary to
distinguish a single octet character and the multiple octet character.
The distinction is done only by first octet.

    Single octet code is:
      0x00-0xFF

* ALGORITHM #2

Against algorithm.1, when the range of the character by tr/// is specified,
only the following character codes are effective.

    Single octet code is:
      0x00-0xFF
