NAME

       Windows1257 - Source code filter for Windows-1257 script (Imitation JPerl)

SYNOPSIS

    In your script:

      use Windows1257;

    At command prompt:

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

DESCRIPTION

      This software is "JPerl on the Modern Perl" written by Perl.

      To our regret, the Sjis software family cannot treat Windows-1257 up to now.
      This software can supplement those weak points. We can write the script
      in Windows-1257 again.

      This software treats Windows-1257 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

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

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

DEPENDENCIES

This software requires perl5.00503 or later.

ABOUT Windows-1257

Windows-1257 (Windows Baltic) is a single byte code page used to support the
Estonian, Latvian and Lithuanian languages under Microsoft Windows.

The label Windows-1257 was registered with the IANA in 1996, citing a publication
of the specification in 1995 and inclusion with pan-European versions of
Windows 95. The later ISO 8859-13 encoding (first published in 1998) is similar,
but differs in reserving the range 0x80-0x9F for control characters, and
accordingly locating certain quotation marks at codepoints 0xA1, 0xA5, 0xB4 and
0xFF instead (the latter two are used for spacing diacritics in Windows-1257).
Windows-1257 is not compatible with the older ISO 8859-4 and ISO 8859-10
encodings.

As with many other code pages, the languages supported in this code page can be
supported in other code pages. The Estonian language can be written with
Windows-1252. It is possible, but unusual, to write Polish, Swedish, Finnish,
Norwegian, Danish and German using this code page. The German specific characters
will be identical to those encoded in Windows-1252.

Unicode is preferred to Windows-1257 in modern applications. 


* 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
