             Summary: Add JSON option to allow unquoted control characters
                 Key: SPARK-21756
                 URL: https://issues.apache.org/jira/browse/SPARK-21756
             Project: Spark
          Issue Type: Improvement
          Components: SQL
    Affects Versions: 2.1.0
            Reporter: Bryan Chen


Hi, we have unquoted control chars in raw json data and the JSON reader just failed at parsing those and complains they are malformed records.

Can we add an allowUnquotedControlChars in JSONOptions for this scenario? The default value would be set to false according to the spec though.

        /**
         * Feature that determines whether parser will allow
         * JSON Strings to contain unquoted control characters
         * (ASCII characters with value less than 32, including
         * tab and line feed characters) or not.
         * If feature is set false, an exception is thrown if such a
         * character is encountered.
         *<p>
         * Since JSON specification requires quoting for all control characters,
         * this is a non-standard feature, and as such disabled by default.
         */
        ALLOW_UNQUOTED_CONTROL_CHARS(false),
