> 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.
> {panel:title=From JacksonParser}
> /**
> * 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.
