JSON parser and generator for C++

RapidJSON is a JSON parser and generator for C++. It was inspired by RapidXml. * It supports both SAX and DOM style API. The SAX parser is only a half thousand lines of code. * It optionally supports SSE2/SSE4.2 for acceleration. * Header-only implementation. It does not depend on STL. * Each JSON value occupies exactly 16/20 bytes for most 32/64-bit machines (excluding text string). By default, it uses a memory allocator, and the parser allocates memory compactly during parsing. * It supports UTF-8, UTF-16, UTF-32 (LE & BE), and their detection, validation and transcoding internally. For example, you can read a UTF-8 file and let RapidJSON transcode the JSON strings into UTF-16 in the DOM. It also supports surrogates and "\u0000" (null character).
