Using mapper configure      JsonReadFeature ALLOW UNESCAPED CONTROL CHARS mappedFeature         true     See javadoc         Feature that determines whether parser will allow    JSON Strings to contain unescaped 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     lt p gt     Since JSON specification requires quoting for all control characters     this is a non-standard feature  and as such disabled by default       Old option JsonParser Feature ALLOW UNQUOTED CONTROL CHARS was deprecated since 2 10  Please see also github thread
