Binding an IRI consisting of special characters can cause a syntax error

[slater2022]

String queryStr = " select ?p ?o  where {  ?s ?p ?o.  }";
try (VirtuosoRepositoryConnection connection = (VirtuosoRepositoryConnection) new VirtuosoRepository("jdbc:virtuoso://localhost:1111", "dba", "dba").getConnection()) {
    TupleQuery tupleQuery = connection.prepareTupleQuery(queryStr);
    tupleQuery.setBinding("s", connection.getValueFactory().createIRI("http://dbpedia.org/resource/北京"));
    TupleQueryResult evaluate = tupleQuery.evaluate();
    while (evaluate.hasNext()) {
        BindingSet bindingSet = evaluate.next();
        System.out.println(bindingSet.getValue("p"));
    }
}

In VirtuosoRepositoryConnection.append(IRI uri, StringBuilder sb, boolean inTriplePattern), escapeString changes queryStr to “ select ?p ?o where { <http://dbpedia.org/resource/\u5317\u4EAC> ?p ?o. }” causing syntax error
