Acknowledgments:

The bulk of the UTF8 / UTF32 conversion and verification comes
from ConvertUTF.[hc]. It has been modified from the original sources.

The original sources were obtained from http://www.unicode.org/.
However, the web site no longer seems to host the files. Instead,
the Unicode FAQ http://www.unicode.org/faq//utf_bom.html#gen4
points to International Components for Unicode (ICU)
http://site.icu-project.org/ as an example of how to write a UTF
converter.

The decision to use the ConvertUTF.[ch] code was made to leverage
"proven" code. Hopefully the local modifications are bug free.

The code in isValidCodePoint() is derived from the ICU code in
utf.h for the macros U_IS_UNICODE_NONCHAR and U_IS_UNICODE_CHAR.

// The following checks are really nothing more than sanity checks.
// JSONKit technically has a few problems from a "strictly C99 conforming" standpoint, though they are of the pedantic nitpicking variety.
// In practice, though, for the compilers and architectures we can reasonably expect this code to be compiled for, these pedantic nitpicks aren't really a problem.
// Since we're limited as to what we can do with pre-processor #if checks, these checks are not nearly as through as they should be.

/*
The NSString and NSData convenience methods need a little bit of explanation.
Prior to JSONKit v1.4, the NSString -objectFromJSONStringWithParseOptions:error: method looked like
const unsigned char *utf8String = (const unsigned char *)[self UTF8String];
if(utf8String == NULL) { return(NULL); }
size_t utf8Length = strlen((const char *)utf8String);
return([[JSONDecoder decoderWithParseOptions:parseOptionFlags] parseUTF8String:utf8String length:utf8Length error:error]);
This changed with v1.4 to a more complicated method. The reason for this is to keep the amount of memory that is
allocated, but not yet freed because it is dependent on the autorelease pool to pop before it can be reclaimed.
In the simpler v1.3 code, this included all the bytes used to store the -UTF8String along with the JSONDecoder and all its overhead.
Now we use an autoreleased CFMutableData that is sized to the UTF8 length of the NSString in question and is used to hold the UTF8
conversion of said string.
Once parsed, the CFMutableData has its length set to 0. This should, hopefully, allow the CFMutableData to realloc and/or free
the buffer.
Another change made was a slight modification to JSONDecoder so that most of the cleanup work that was done in -dealloc was moved
to a private, internal function. These convenience routines keep the pointer to the autoreleased JSONDecoder and calls
_JSONDecoderCleanup() to early release the decoders resources since we already know that particular decoder is not going to be used
again.
If everything goes smoothly, this will most likely result in perhaps a few hundred bytes that are allocated but waiting for the
autorelease pool to pop. This is compared to the thousands and easily hundreds of thousands of bytes that would have been in
autorelease limbo. It's more complicated for us, but a win for the user.
Autorelease objects are used in case things don't go smoothly. By having them autoreleased, we effectively guarantee that our
requirement to -release the object is always met, not matter what goes wrong. The downside is having a an object or two in
autorelease limbo, but we've done our best to minimize that impact, so it all balances out.

  // We need to work around a bug in 10.7, which breaks ABI compatibility with Objective-C going back not just to 10.0, but OpenStep and even NextStep.
  //
  // It has long been documented that "the very first thing that a pointer to an Objective-C object "points to" is a pointer to that objects class".
  //
  // This is euphemistically called "tagged pointers". There are a number of highly technical problems with this, most involving long passages from
  // the C standard(s). In short, one can make a strong case, couched from the perspective of the C standard(s), that that 10.7 "tagged pointers" are
  // fundamentally Wrong and Broken, and should have never been implemented. Assuming those points are glossed over, because the change is very clearly
  // breaking ABI compatibility, this should have resulted in a minimum of a "minimum version required" bump in various shared libraries to prevent
  // causes code that used to work just fine to suddenly break without warning.
  //
  // In fact, the C standard says that the hack below is "undefined behavior"- there is no requirement that the 10.7 tagged pointer hack of setting the
  // "lower, unused bits" must be preserved when casting the result to an integer type, but this "works" because for most architectures
  // `sizeof(long) == sizeof(void *)` and the compiler uses the same representation for both. (note: this is informal, not meant to be
  // normative or pedantically correct).
  //
  // In other words, while this "works" for now, technically the compiler is not obligated to do "what we want", and a later version of the compiler
  // is not required in any way to produce the same results or behavior that earlier versions of the compiler did for the statement below.
  //
  // Fan-fucking-tastic.
  //
  // Why not just use `object_getClass()`? Because `object->isa` reduces to (typically) a *single* instruction. Calling `object_getClass()` requires
  // that the compiler potentially spill registers, establish a function call frame / environment, and finally execute a "jump subroutine" instruction.
  // Then, the called subroutine must spend half a dozen instructions in its prolog, however many instructions doing whatever it does, then half a dozen
  // instructions in its prolog. One instruction compared to dozens, maybe a hundred instructions.
  //
  // Yes, that's one to two orders of magnitude difference. Which is compelling in its own right. When going for performance, you're often happy with
  // gains in the two to three percent range.
