This operator returns a JSON-encoded UTF-8 version of the data string. The apostrophe (straight single quote), straight double quote, solidus (forward slash) and backslash characters are all escaped by a preceding backslash character. The control characters backspace, form feed, new line, carriage return, horizontal tab are encoded as standard JavaScript escapes (\b, \f, \n, \r\, \t ). Unicode addresses are also escaped: \u2345.

Note: the single apostrophe (straight quote) is not escaped as this can cause some Ajax functions to fail.

For string-type data, see also the '.json' operator.

jsonEncode() does not escape single straight quotation marks.
