correct unicode handling
.Sp
This module knows how to handle Unicode (depending on Perl version).
.Sp
See to \*(L"A \s-1FEW NOTES ON UNICODE AND PERL\*(R"\s0 in \s-1JSON::XS\s0 and \*(L"\s-1UNICODE HANDLING ON PERLS\*(R"\s0.
.IP "\(bu" 4
round-trip integrity
.Sp
When you serialise a perl data structure using only data types supported
by \s-1JSON\s0 and Perl, the deserialised data structure is identical on the Perl
level. (e.g. the string \*(L"2.0\*(R" doesn't suddenly become \*(L"2\*(R" just because
it looks like a number). There \fIare\fR minor exceptions to this, read the
\&\s-1MAPPING\s0 section below to learn about those.
.IP "\(bu" 4
strict checking of \s-1JSON\s0 correctness
.Sp
There is no guessing, no generating of illegal \s-1JSON\s0 texts by default,
and only \s-1JSON\s0 is accepted as input by default (the latter is a security feature).
But when some options are set, loose checking features are available.

.SH "HOW DO I DECODE A DATA FROM OUTER AND ENCODE TO OUTER"
.IX Header "HOW DO I DECODE A DATA FROM OUTER AND ENCODE TO OUTER"
This section supposes that your perl version is 5.8 or later.
.PP
If you know a \s-1JSON\s0 text from an outer world \- a network, a file content, and so on,
is encoded in \s-1UTF\-8,\s0 you should use \f(CW\*(C`decode_json\*(C'\fR or \f(CW\*(C`JSON\*(C'\fR module object
with \f(CW\*(C`utf8\*(C'\fR enabled. And the decoded result will contain \s-1UNICODE\s0 characters.
.PP
.Vb 4
\&  # from network
\&  my $json        = JSON::PP\->new\->utf8;
\&  my $json_text   = CGI\->new\->param( \*(Aqjson_data\*(Aq );
\&  my $perl_scalar = $json\->decode( $json_text );
\&  
\&  # from file content
\&  local $/;
\&  open( my $fh, \*(Aq<\*(Aq, \*(Aqjson.data\*(Aq );
\&  $json_text   = <$fh>;
\&  $perl_scalar = decode_json( $json_text );
.Ve
.PP
If an outer data is not encoded in \s-1UTF\-8,\s0 firstly you should \f(CW\*(C`decode\*(C'\fR it.
.PP
.Vb 5
\&  use Encode;
\&  local $/;
\&  open( my $fh, \*(Aq<\*(Aq, \*(Aqjson.data\*(Aq );
\&  my $encoding = \*(Aqcp932\*(Aq;
\&  my $unicode_json_text = decode( $encoding, <$fh> ); # UNICODE
\&  
\&  # or you can write the below code.
\&  #
\&  # open( my $fh, "<:encoding($encoding)", \*(Aqjson.data\*(Aq );
\&  # $unicode_json_text = <$fh>;
.Ve
.PP
In this case, \f(CW$unicode_json_text\fR is of course \s-1UNICODE\s0 string.
So you \fBcannot\fR use \f(CW\*(C`decode_json\*(C'\fR nor \f(CW\*(C`JSON\*(C'\fR module object with \f(CW\*(C`utf8\*(C'\fR enabled.
Instead of them, you use \f(CW\*(C`JSON\*(C'\fR module object with \f(CW\*(C`utf8\*(C'\fR disable.
.PP
.Vb 1
\&  $perl_scalar = $json\->utf8(0)\->decode( $unicode_json_text );
.Ve
.PP
Or \f(CW\*(C`encode \*(Aqutf8\*(Aq\*(C'\fR and \f(CW\*(C`decode_json\*(C'\fR:
.PP
.Vb 2
\&  $perl_scalar = decode_json( encode( \*(Aqutf8\*(Aq, $unicode_json_text ) );
\&  # this way is not efficient.
.Ve
.PP
And now, you want to convert your \f(CW$perl_scalar\fR into \s-1JSON\s0 data and
send it to an outer world \- a network or a file content, and so on.
.PP
Your data usually contains \s-1UNICODE\s0 strings and you want the converted data to be encoded
in \s-1UTF\-8,\s0 you should use \f(CW\*(C`encode_json\*(C'\fR or \f(CW\*(C`JSON\*(C'\fR module object with \f(CW\*(C`utf8\*(C'\fR enabled.
.PP
.Vb 3
\&  print encode_json( $perl_scalar ); # to a network? file? or display?
\&  # or
\&  print $json\->utf8\->encode( $perl_scalar );
.Ve
.PP
If \f(CW$perl_scalar\fR does not contain \s-1UNICODE\s0 but \f(CW$encoding\fR\-encoded strings
for some reason, then its characters are regarded as \fBlatin1\fR for perl
(because it does not concern with your \f(CW$encoding\fR).
You \fBcannot\fR use \f(CW\*(C`encode_json\*(C'\fR nor \f(CW\*(C`JSON\*(C'\fR module object with \f(CW\*(C`utf8\*(C'\fR enabled.
Instead of them, you use \f(CW\*(C`JSON\*(C'\fR module object with \f(CW\*(C`utf8\*(C'\fR disable.
Note that the resulted text is a \s-1UNICODE\s0 string but no problem to print it.
.PP
.Vb 4
\&  # $perl_scalar contains $encoding encoded string values
\&  $unicode_json_text = $json\->utf8(0)\->encode( $perl_scalar );
\&  # $unicode_json_text consists of characters less than 0x100
\&  print $unicode_json_text;
.Ve
.PP
Or \f(CW\*(C`decode $encoding\*(C'\fR all string values and \f(CW\*(C`encode_json\*(C'\fR:
.PP
.Vb 3
\&  $perl_scalar\->{ foo } = decode( $encoding, $perl_scalar\->{ foo } );
\&  # ... do it to each string values, then encode_json
\&  $json_text = encode_json( $perl_scalar );
.Ve
.PP
This method is a proper way but probably not efficient.
.PP

.PP
If \f(CW$enable\fR is true (or missing), then the encode method will not generate characters outside
the code range 0..127. Any Unicode characters outside that range will be escaped using either
a single \euXXXX or a double \euHHHH\euLLLLL escape sequence, as per \s-1RFC4627.
\&\s0(See to \*(L"OBJECT-ORIENTED \s-1INTERFACE\*(R"\s0 in \s-1JSON::XS\s0).
.PP
In Perl 5.005, there is no character having high value (more than 255).
See to \*(L"\s-1UNICODE HANDLING ON PERLS\*(R"\s0.
.PP
If \f(CW$enable\fR is false, then the encode method will not escape Unicode characters unless
required by the \s-1JSON\s0 syntax or other flags. This results in a faster and more compact format.
.PP
.Vb 2

If \f(CW$enable\fR is true (or missing), then the encode method will encode the resulting \s-1JSON\s0
text as latin1 (or iso\-8859\-1), escaping any characters outside the code range 0..255.

If \f(CW$enable\fR is true (or missing), then the encode method will encode the \s-1JSON\s0 result
into \s-1UTF\-8,\s0 as required by many protocols, while the decode method expects to be handled
an UTF\-8\-encoded string. Please note that UTF\-8\-encoded strings do not contain any
characters outside the range 0..255, they are thus useful for bytewise/binary I/O.

When \f(CW$coderef\fR is specified, it will be called from \f(CW\*(C`decode\*(C'\fR each

a single scalar (which need not be a reference), this value

deserialised data structure. If it returns an empty list

Works remotely similar to \f(CW\*(C`filter_json_object\*(C'\fR, but is only called for
\&\s-1JSON\s0 objects having a single key named \f(CW$key\fR.
.PP
This \f(CW$coderef\fR is called before the one specified via
\&\f(CW\*(C`filter_json_object\*(C'\fR, if any. It gets passed the single value in the \s-1JSON\s0
object. If it returns a single value, it will be inserted into the data
structure. If it returns nothing (not even \f(CW\*(C`undef\*(C'\fR but the empty list),
the callback from \f(CW\*(C`filter_json_object\*(C'\fR will be called next, as if no
single-key callback were specified.
.PP
If \f(CW$coderef\fR is omitted or undefined, the corresponding callback will be
disabled. There can only ever be one callback for a given key.
.PP
As this callback gets called less often then the \f(CW\*(C`filter_json_object\*(C'\fR
one, decoding speed will not usually suffer as much. Therefore, single-key
objects make excellent targets to serialise Perl objects into, especially
as single-key \s-1JSON\s0 objects are as close to the type-tagged value concept
as \s-1JSON\s0 gets (it's basically an \s-1ID/VALUE\s0 tuple). Of course, \s-1JSON\s0 does not
support this in any way, so you need to make sure your data never looks
like a serialised Perl hash.
.PP
Typical names for the single object key are \f(CW\*(C`_\|_class_whatever_\|_\*(C'\fR, or
\&\f(CW\*(C`$_\|_dollars_are_rarely_used_\|_$\*(C'\fR or \f(CW\*(C`}ugly_brace_placement\*(C'\fR, or even
things like \f(CW\*(C`_\|_class_md5sum(classname)_\|_\*(C'\fR, to reduce the risk of clashing
with real hashes.

Example, decode \s-1JSON\s0 objects of the form \f(CW\*(C`{ "_\|_widget_\|_" => <id> }\*(C'\fR

.IX Header "INCREMENTAL PARSING"
Most of this section are copied and modified from \*(L"\s-1INCREMENTAL PARSING\*(R"\s0 in \s-1JSON::XS\s0.
.PP
In some cases, there is the need for incremental parsing of \s-1JSON\s0 texts.
This module does allow you to parse a \s-1JSON\s0 stream incrementally.
It does so by accumulating text until it has a full \s-1JSON\s0 object, which
it then can decode. This process is similar to using \f(CW\*(C`decode_prefix\*(C'\fR
to see if a full \s-1JSON\s0 object is available, but is much more efficient
(and can be implemented with a minimum of method calls).
.PP
This module will only attempt to parse the \s-1JSON\s0 text once it is sure it
has enough text to get a decisive result, using a very simple but
truly incremental parser. This means that it sometimes won't stop as
early as the full parser, for example, it doesn't detect parentheses
mismatches. The only thing it guarantees is that it starts decoding as
soon as a syntactically valid \s-1JSON\s0 text has been seen. This means you need
to set resource limits (e.g. \f(CW\*(C`max_size\*(C'\fR) to ensure the parser will stop
parsing in the presence if syntax errors.
.PP
The following methods implement this incremental parser.
.SS "incr_parse"
.IX Subsection "incr_parse"
.Vb 1
\&    $json\->incr_parse( [$string] ) # void context
\&    
\&    $obj_or_undef = $json\->incr_parse( [$string] ) # scalar context
\&    
\&    @obj_or_empty = $json\->incr_parse( [$string] ) # list context
.Ve
.PP
This is the central parsing function. It can both append new text and
extract objects from the stream accumulated so far (both of these
functions are optional).
.PP
If \f(CW$string\fR is given, then this string is appended to the already
existing \s-1JSON\s0 fragment stored in the \f(CW$json\fR object.
.PP
After that, if the function is called in void context, it will simply
return without doing anything further. This can be used to add more text
in as many chunks as you want.
.PP
If the method is called in scalar context, then it will try to extract
exactly \fIone\fR \s-1JSON\s0 object. If that is successful, it will return this
object, otherwise it will return \f(CW\*(C`undef\*(C'\fR. If there is a parse error,
this method will croak just as \f(CW\*(C`decode\*(C'\fR would do (one can then use
\&\f(CW\*(C`incr_skip\*(C'\fR to skip the erroneous part). This is the most common way of
using the method.
.PP
And finally, in list context, it will try to extract as many objects
from the stream as it can find and return them, or the empty list
otherwise. For this to work, there must be no separators between the \s-1JSON\s0
objects or arrays, instead they must be concatenated back-to-back. If
an error occurs, an exception will be raised as in the scalar context
case. Note that in this case, any previously-parsed \s-1JSON\s0 texts will be
lost.
.PP
Example: Parse some \s-1JSON\s0 arrays/objects in a given string and return them.

\&    $lvalue_string = $json\->incr_text

.PP
This method returns the currently stored \s-1JSON\s0 fragment as an lvalue, that
is, you can manipulate it. This \fIonly\fR works when a preceding call to
\&\f(CW\*(C`incr_parse\*(C'\fR in \fIscalar context\fR successfully returned an object. Under
all other circumstances you must not call this function (I mean it.
although in simple tests it might actually work, it \fIwill\fR fail under
real world conditions). As a special exception, you can also call this
method before having parsed anything.
.PP
This function is useful in two cases: a) finding the trailing text after a
\&\s-1JSON\s0 object or b) parsing multiple \s-1JSON\s0 objects separated by non-JSON text
(such as commas).

.IX Subsection "JSON -> PERL"
.IP "object" 4
.IX Item "object"
A \s-1JSON\s0 object becomes a reference to a hash in Perl. No ordering of object
keys is preserved (\s-1JSON\s0 does not preserver object key ordering itself).
.IP "array" 4
.IX Item "array"
A \s-1JSON\s0 array becomes a reference to an array in Perl.
.IP "string" 4
.IX Item "string"
A \s-1JSON\s0 string becomes a string scalar in Perl \- Unicode codepoints in \s-1JSON\s0
are represented by the same codepoints in the Perl string, so no manual
decoding is necessary.
.IP "number" 4
.IX Item "number"
A \s-1JSON\s0 number becomes either an integer, numeric (floating point) or
string scalar in perl, depending on its range and any fractional parts. On
the Perl level, there is no difference between those as Perl handles all
the conversion details, but an integer may take slightly less memory and
might represent more values exactly than floating point numbers.
.Sp
If the number consists of digits only, \f(CW\*(C`JSON\*(C'\fR will try to represent
it as an integer value. If that fails, it will try to represent it as
a numeric (floating point) value if that is possible without loss of
precision. Otherwise it will preserve the number as a string value (in
which case you lose roundtripping ability, as the \s-1JSON\s0 number will be
re-encoded to a \s-1JSON\s0 string).
.Sp
Numbers containing a fractional or exponential part will always be
represented as numeric (floating point) values, possibly at a loss of
precision (in which case you might lose perfect roundtripping ability, but
the \s-1JSON\s0 number will still be re-encoded as a \s-1JSON\s0 number).
.Sp
Note that precision is not accuracy \- binary floating point values cannot
represent most decimal fractions exactly, and when converting from and to
floating point, \f(CW\*(C`JSON\*(C'\fR only guarantees precision up to but not including
the least significant bit.
.Sp
When \f(CW\*(C`allow_bignum\*(C'\fR is enabled, the big integers 
and the numeric can be optionally converted into Math::BigInt and
Math::BigFloat objects.
.IP "true, false" 4
.IX Item "true, false"
These \s-1JSON\s0 atoms become \f(CW\*(C`JSON::PP::true\*(C'\fR and \f(CW\*(C`JSON::PP::false\*(C'\fR,
respectively. They are overloaded to act almost exactly like the numbers
\&\f(CW1\fR and \f(CW0\fR. You can check whether a scalar is a \s-1JSON\s0 boolean by using
the \f(CW\*(C`JSON::is_bool\*(C'\fR function.

.SS "\s-1PERL \-\s0> \s-1JSON\s0"
.IX Subsection "PERL -> JSON"
The mapping from Perl to \s-1JSON\s0 is slightly more difficult, as Perl is a
truly typeless language, so we can only guess which \s-1JSON\s0 type is meant by
a Perl value.
.IP "hash references" 4
.IX Item "hash references"
Perl hash references become \s-1JSON\s0 objects. As there is no inherent ordering
in hash keys (or \s-1JSON\s0 objects), they will usually be encoded in a
pseudo-random order that can change between runs of the same program but
stays generally the same within a single run of a program. \f(CW\*(C`JSON\*(C'\fR
optionally sort the hash keys (determined by the \fIcanonical\fR flag), so
the same datastructure will serialise to the same \s-1JSON\s0 text (given same
settings and version of \s-1JSON::XS\s0), but this incurs a runtime overhead
and is only rarely useful, e.g. when you want to compare some \s-1JSON\s0 text
against another for equality.
.IP "array references" 4
.IX Item "array references"
Perl array references become \s-1JSON\s0 arrays.
.IP "other references" 4

Other unblessed references are generally not allowed and will cause an
exception to be thrown, except for references to the integers \f(CW0\fR and
\&\f(CW1\fR, which get turned into \f(CW\*(C`false\*(C'\fR and \f(CW\*(C`true\*(C'\fR atoms in \s-1JSON.\s0 You can
also use \f(CW\*(C`JSON::false\*(C'\fR and \f(CW\*(C`JSON::true\*(C'\fR to improve readability.

respectively. You can also use \f(CW\*(C`\e1\*(C'\fR and \f(CW\*(C`\e0\*(C'\fR directly if you want.
.Sp
JSON::PP::null returns \f(CW\*(C`undef\*(C'\fR.

Blessed objects are not directly representable in \s-1JSON.\s0 See the
\&\f(CW\*(C`allow_blessed\*(C'\fR and \f(CW\*(C`convert_blessed\*(C'\fR methods on various options on
how to deal with this: basically, you can choose between throwing an
exception, encoding the reference as if it weren't blessed, or provide
your own serialiser method.
.Sp
See to convert_blessed.
.IP "simple scalars" 4
.IX Item "simple scalars"
Simple Perl scalars (any scalar that is not a reference) are the most
difficult objects to encode: \s-1JSON::XS\s0 and \s-1JSON::PP\s0 will encode undefined scalars as
\&\s-1JSON \s0\f(CW\*(C`null\*(C'\fR values, scalars that have last been used in a string context
before encoding as \s-1JSON\s0 strings, and anything else as number value:
.Sp
.Vb 4
\&   # dump as number
\&   encode_json [2]                      # yields [2]
\&   encode_json [\-3.0e17]                # yields [\-3e+17]
\&   my $value = 5; encode_json [$value]  # yields [5]
\&
\&   # used as string, so dump as string
\&   print $value;
\&   encode_json [$value]                 # yields ["5"]
\&
\&   # undef becomes null
\&   encode_json [undef]                  # yields [null]
.Ve
.Sp
You can force the type to be a string by stringifying it:
.Sp
.Vb 4
\&   my $x = 3.1; # some variable containing a number
\&   "$x";        # stringified
\&   $x .= "";    # another, more awkward way to stringify
\&   print $x;    # perl does it for you, too, quite often
.Ve
.Sp
You can force the type to be a number by numifying it:
.Sp
.Vb 3
\&   my $x = "3"; # some variable containing a string
\&   $x += 0;     # numify it, ensuring it will be dumped as a number
\&   $x *= 1;     # same thing, the choice is yours.
.Ve
.Sp
You cannot currently force the type in other, less obscure, ways.
.Sp
Note that numerical precision has the same meaning as under Perl (so
binary to decimal conversion follows the same rules as in Perl, which
can differ to other languages). Also, your perl interpreter might expose
extensions to the floating point numbers of your platform, such as
infinities or NaN's \- these cannot be represented in \s-1JSON,\s0 and it is an
error to pass those in.
