----------------------------------------
BTW the same seems to happen using RDF Delta:
{code:java}
[line: 1276, col: 437] Unicode replacement character U+FFFD.
org.apache.jena.riot.RiotParseException: [line: 1276, col: 428] Unicode

> TDB throws Unicode Replacement Character exception while fetching data

> Key: JENA-2179

> Project: Apache Jena
> Issue Type: Bug
> Components: TDB
> Affects Versions: Jena 4.2.0
> Reporter: Holger Knublauch
> Assignee: Andy Seaborne
> Priority: Major
> Fix For: Jena 4.3.0

> Attachments: TBS4190_Test.java

> This seems to have been introduced with
> https://issues.apache.org/jira/browse/JENA-2120
> With TDB databases that contain the replacement character in a literal, the
> warnings are reported as Exceptions. We have seen this:
> {code:java}
> WARN [http-nio-8083-exec-10] g.e.SimpleDataFetcherExceptionHandler -
> Exception while fetching data (/resources[0]/turtleSourceCode) : [line: 1,

> TDB seems to use the fallback error handler causing an exception to be thrown
> instead of just printing the warning (to the log).
> Richard says he believes a fix would be to change NodecSEE.createTokenizer():
> {code:java}
> return TokenizerText.create()
> .fromString(string)
> .errorHandler(ErrorHandlerFactory.errorHandlerDetailed())
> .build();
> {code}
> Is there any known work-around in 4.2.0? We cannot even query those triples
> from the offending TDBs at the moment.
