Description
When using the NTriplesWriter, I wanted to configure it to write unicode points as escape sequences. I tried to subclass org.apache.any23.writer.TripleHandler and overwrite the access to the org.eclipse.rdf4j.rio.ntriples.NTriplesWriter but couldn't do that since the access to the NTriplesWriter is package protected. I ended up copying the code which seems a bit clunky...
I was asked to create a pull request, this issue is there to track that.
