    Description

      According to RFC 4627 http://www.ietf.org/rfc/rfc4627.txt

      "All Unicode characters may be placed within the quotation marks except for the characters that must be escaped: quotation mark, reverse solidus, and the control characters (U+0000 through U+001F)."

      If you store a string that contains a control character in a dynamic column and fetch it back with COLUMN_JSON() then the control character is not escaped in the JSON encoded value returned.

      All the JSON decoders I have tried it with fail on such strings.
