-------------------------------------
BTW:
{{RDFParserBuilder.create().source(new ByteArrayInputStream}}
can be written
{{RDFParser.fromString}}
> Escape % in TokenizerText#fatal

> Key: JENA-2188
> URL: https://issues.apache.org/jira/browse/JENA-2188
> Project: Apache Jena
> Issue Type: Bug
> Components: RIOT
> Affects Versions: Jena 4.2.0
> Reporter: Jan Martin Keil
> Assignee: Andy Seaborne
> Priority: Major
>
> The presence of "%" near to a syntax error might cause _TokenizerText#fatal_
> to throw an _UnknownFormatConversionException_ instead of a
> _RiotParseException_. This happens because of the use of _String#format_
> without escaping "%". See the following example with an intended syntax error
> (additional " after lang-tag):
> {code:java}
> import java.io.ByteArrayInputStream;
> import static java.nio.charset.StandardCharsets.UTF_8;
> import org.apache.jena.rdf.model.ModelFactory;
> import org.apache.jena.riot.Lang;
> import org.apache.jena.riot.RDFParserBuilder;
> import org.junit.jupiter.api.Test;
> public class TokenizerTextTest {
> @Test
> public void fatal() {
> RDFParserBuilder.create().source(new ByteArrayInputStream(
> "<http://example.org/s> <http://example.org/p> \"example\"@en-US\"
> <http://example.org/%D8-graph>"
>
> .getBytes(UTF_8))).lang(Lang.NQUADS).parse(ModelFactory.createDefaultModel());
> }
> }{code}
> This causes:
> {code:java}
> java.util.UnknownFormatConversionException: Conversion = 'D'
