JSON Valid Chars

Question

Is the presence of double quotes “invalid” in the context of the JSON response? Is there a specific JSON specification that could give me an answer?

Answer 1

Check http://www.json.org/ and scroll down to the "String" chart.

You can see how \ is the "control" character. If you need a literal backslash in your JSON, you need to avoid it: "\\"is a valid JSON string, for example.
