(1) Time of escape script for old byte-oriented perl.

Someday, I want to ask Larry Wall about this goal in the elevator.

=item * Goal #4:

Perl should remain one language, rather than forking into a
byte-oriented Perl and a character-oriented Perl.

JPerl remains one Perl language by forking to two interpreters.
However, the Perl core team did not desire fork of the interpreter.
As a result, Perl language forked contrary to goal #4.

A character-oriented perl is not necessary to make it specially,
because a byte-oriented perl can already treat the binary data.
This software is only an application program of byte-oriented Perl,
a filter program.

And you will get support from the Perl community, when you solve the
problem by the Perl script.

Arabic software remains one language and one interpreter.

=item * Goal #5:

JPerl users will be able to maintain JPerl by Perl.

May the JPerl be with you, always.

Back when Programming Perl, 3rd ed. was written, UTF8 flag was not born
and Perl is designed to make the easy jobs easy. This software provides
programming environment like at that time.

=head1 Perl's motto

   Some computer scientists (the reductionists, in particular) would
  like to deny it, but people have funny-shaped minds. Mental geography
  is not linear, and cannot be mapped onto a flat surface without
  severe distortion. But for the last score years or so, computer
  reductionists have been first bowing down at the Temple of Orthogonality,
  then rising up to preach their ideas of ascetic rectitude to any who
  would listen.
 
   Their fervent but misguided desire was simply to squash your mind to
  fit their mindset, to smush your patterns of thought into some sort of
  Hyperdimensional Flatland. It's a joyless existence, being smushed.

  If you think this is a big headache, you're right. No one likes
  this situation, but Perl does the best it can with the input and
  encodings it has to deal with. If only we could reset history and
  not make so many mistakes next time.

   The most important thing for most people to know about handling
  Unicode data in Perl, however, is that if you don't ever use any Uni-
  code data -- if none of your files are marked as UTF-8 and you don't
  use UTF-8 locales -- then you can happily pretend that you're back in
  Perl 5.005_03 land; the Unicode features will in no way interfere with
  your code unless you're explicitly using them. Sometimes the twin
  goals of embracing Unicode but not disturbing old-style byte-oriented
  scripts has led to compromise and confusion, but it's the Perl way to
  silently do the right thing, which is what Perl ends up doing.
