* Rapidjson is memory friendly. Each JSON value occupies exactly 16/20 bytes for most 32/64-bit machines (excluding text string). By default it uses a fast memory allocator, and the parser allocates memory compactly during parsing.

* Rapidjson is Unicode friendly. It supports UTF-8, UTF-16, UTF-32 (LE & BE), and their detection, validataton 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).
