Unicode problem after regenerating

[kkzhang]

A json string eg.

{"test": "\u4f60\u597d"}

parse it jsonObj = JSON.parse(s), then generate it newStr = JSON.generate(jsonObj)

the content of "newStr" is now

{"test": "你好"}

which is supposed to be identical with the original string( {"test": "\u4f60\u597d"} ).
