Dear Andy, Thanks for your pointing it out! IRILib.encodeUriComponent(String) works well.
Is there a tool in the Jena code base for parsing String to Jena Literal for different data types? For example: 1) "65000" -> "65000"^^<http://www.w3.org/2001/XMLSchema#integer> 2) "65000.123" -> "65000.123"^^<http://www.w3.org/2001/XMLSchema#double> 3) "true" -> "true"^^<http://www.w3.org/2001/XMLSchema#boolean> There would be more advanced features like parsing date/time to xsd:date or xsd:dateTime for CSV values. The NodeFactory.createLiteral() method does not provide these features.
