+=head1 The UTF-8 flag
+
+Before the introduction of utf8 support in perl, The C<eq> operator
+just compares internal data of the scalars. Now C<eq> means internal
+data equality AND I<the utf8 flag>. To explain why we made it so, I
+will quote page 402 of C<Programming Perl, 3rd ed.>
+
+=over 2
+
+=item Goal #1:
+
+Old byte-oriented programs should not spontaneously break on the old
+byte-oriented data they used to work on.
+
+=item Goal #2:
+
+Old byte-oriented programs should magically start working on the new
+character-oriented data when appropriate.
+
+=item Goal #3:
+
+Programs should run just as fast in the new character-oriented mode
+as in the old byte-oriented mode.
+
+=item Goal #4:
+
+Perl should remain one language, rather than forking into a
+byte-oriented Perl and a character-oriented Perl.
+
+=back
+
+Back when C<Programming Perl, 3rd ed.> was written, not even Perl 5.6.0
+was born and many features documented in the book remained
+unimplemented. Perl 5.8 hopefully correct this and the introduction
+of UTF-8 flag is one of them. You can think this perl notion of
+byte-oriented mode (utf8 flag off) and character-oriented mode (utf8
+flag on).
+
+Here is how Encode takes care of the utf8 flag.
+
+=over2
+
+=item *
+
+When you encode, the resulting utf8 flag is always off.
+
+=item
+
+When you decode, the resuting utf8 flag is on unless you can
+unambiguously represent data. Here is the definition of
+dis-ambiguity.
+
+ After C<$utf8 = decode('foo', $octet);>,
+
+ When $octet is... The utf8 flag in $utf8 is
+ ---------------------------------------------
+ In ASCII only (or EBCDIC only) OFF
+ In ISO-8859-1 ON
+ In any other Encoding ON
+ ---------------------------------------------
+
+As you see, there is one exception, In ASCII. That way you can assue
+Goal #1. And with Encode Goal #2 is assumed but you still have to be
+careful in such cases mentioned in B<CAVEAT> paragraphs.
+
+This utf8 flag is not visible in perl scripts, exactly for the same
+reason you cannot (or you I<don't have to>) see if a scalar contains a
+string, integer, or floating point number. But you can still peek
+and poke these if you will. See the section below.

+ # if you are sure $data won't contain anything bogus
+
+ use Encode::Guess qw/euc-jp shiftjis 7bit-jis/;
+ my $utf8 = decode("Guess", $data);
+ my $data = encode("Guess", $utf8); # this doesn't work!

+ # more elaborate way

+ $utf8 = $enc->decode($data);
+ # or
+ $utf8 = decode($enc->name, $data)
+
+=head1 ABSTRACT
+
+Encode::Guess enables you to guess in what encoding a given data is
+encoded, or at least tries to.
+
+=head1 DESCRIPTION
+
+By default, it checks only ascii, utf8 and UTF-16/32 with BOM.
+
+ use Encode::Guess; # ascii/utf8/BOMed UTF
+
+To use it more practically, you have to give the names of encodings to
+check (I<suspects> as follows). The name of suspects can either be
+canonical names or aliases.
+
+ # tries all major Japanese Encodings as well
+ use Encode::Guess qw/euc-jp shiftjis 7bit-jis/;
+
+=over 4
+
+=item Encode::Guess->set_suspects
+
+You can also change the internal suspects list via C<set_suspects>
+method.
+
+ use Encode::Guess;
+ Encode::Guess->set_suspects(qw/euc-jp shiftjis 7bit-jis/);
+
+=item Encode::Guess->add_suspects
+
+Or you can use C<add_suspects> method. The difference is that
+C<set_suspects> flushes the current suspects list while
+C<add_suspects> adds.
+
+ use Encode::Guess;
+ Encode::Guess->add_suspects(qw/euc-jp shiftjis 7bit-jis/);
+ # now the suspects are euc-jp,shiftjis,7bit-jis, AND
+ # euc-kr,euc-cn, and big5-eten
+ Encode::Guess->add_suspects(qw/euc-kr euc-cn big5-eten/);
+
+=item Encode::decode("Guess" ...)
+
+When you are content with suspects list, you can now
+
+ my $utf8 = Encode::decode("Guess", $data);
+
+=item Encode::Guess->guess($data)
+
+But it will croak if Encode::Guess fails to eliminate all other
+suspects but the right one or no suspect was good. So you should
+instead try this;
+
+ my $decoder = Encode::Guess->guess($data);
+
+On success, $decoder is an object that is documented in
+L<Encode::Encoding>. So you can now do this;
+
+ my $utf8 = $decoder->decode($data);
+
+On failure, $decoder now contains an error message so the whole thing
+would be as follows;
+
+ my $decoder = Encode::Guess->guess($data);
+ die $decoder unless ref($decoder);
+ my $utf8 = $decoder->decode($data);
+
+=item guess_encoding($data, [, I<list of suspects>])
+
+You can also try C<guess_encoding> function which is exported by
+default. It takes $data to check and it also takes the list of
+suspects by option. The optional suspect list is I<not reflected> to
+the internal suspects list.
+
+ my $decoder = guess_encoding($data, qw/euc-jp euc-kr euc-cn/);
+ die $decoder unless ref($decoder);
+ my $utf8 = $decoder->decode($data);
+ # check only ascii and utf8
+ my $decoder = guess_encoding($data);
+
+=back
+
+=head1 CAVEATS
+
+=over 4
+
+=item *
+
+Because of the algorithm used, ISO-8859 series and other single-byte
+encodings do not work well unless either one of ISO-8859 is the only
+one suspect (besides ascii and utf8).
+
+ use Encode::Guess;
+ # perhaps ok
+ my $decoder = guess_encoding($data, 'latin1');
+ # definitely NOT ok
+ my $decoder = guess_encoding($data, qw/latin1 greek/);
+
+The reason is that Encode::Guess guesses encoding by trial and error.
+It first splits $data into lines and tries to decode the line for each
+suspect. It keeps it going until all but one encoding was eliminated
+out of suspects list. ISO-8859 series is just too successful for most
+cases (because it fills almost all code points in \x00-\xff).
+
+=item *
+
+Do not mix national standard encodings and the corresponding vendor
+encodings.
+
+ # a very bad idea
+ my $decoder
+ = guess_encoding($data, qw/shiftjis MacJapanese cp932/);
+
+The reason is that vendor encoding is usually a superset of national
+standard so it becomes too ambiguous for most cases.
+
+=item *
+
+On the other hand, mixing various national standard encodings
+automagically works unless $data is too short to allow for guessing.
+
+ # This is ok if $data is long enough
+ my $decoder =
+ guess_encoding($data, qw/euc-cn
+ euc-jp shiftjis 7bit-jis
+ euc-kr
+ big5-eten/);
+
+=item *
+
+DO NOT PUT TOO MANY SUSPECTS! Don't you try something like this!
+
+ my $decoder = guess_encoding($data,
+ Encode->encodings(":all"));
+
+=back
+
+It is, after all, just a guess. You should alway be explicit when it
+comes to encodings. But there are some, especially Japanese,
+environment that guess-coding is a must. Use this module with care.
