-
- 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.

-// JSONKit v1.4 used both a JKArray : NSArray and JKMutableArray : NSMutableArray, and the same for the dictionary collection type.
-// However, Louis Gerbarg (via cocoa-dev) pointed out that Cocoa / Core Foundation actually implements only a single class that inherits from the
-// mutable version, and keeps an ivar bit for whether or not that instance is mutable. This means that the immutable versions of the collection
-// classes receive the mutating methods, but this is handled by having those methods throw an exception when the ivar bit is set to immutable.
-// We adopt the same strategy here. It's both cleaner and gets rid of the method swizzling hackery used in JSONKit v1.4.
-
-
-// This is a workaround for issue #23 https://github.com/johnezang/JSONKit/pull/23
-// Basically, there seem to be a problem with using +load in static libraries on iOS. However, __attribute__ ((constructor)) does work correctly.
-// Since we do not require anything "special" that +load provides, and we can accomplish the same thing using __attribute__ ((constructor)), the +load logic was moved here.
