Issue validity

This issue first occurred in a monthly job on 2023-04-10. So the problem earliest exists since 2023-03-10.

Error Description

Some object IRIs of foaf:depiction statements contain the character Newline (U+000A = \n).
I think, this occurs in statements extracted from <gallery>, if the previous image caption ended with a link.
I think, this is not related to #562, as the error is not caused by a character of the IRI, but the context it was extracted from.

Pinpointing the source of the error

I noticed the problem in the SPARQL endpoint: e.g. https://dbpedia.org/sparql/?default-graph-uri=http%3A%2F%2Fdbpedia.org&query=DESCRIBE+%3Chttp%3A%2F%2Fdbpedia.org%2Fresource%2FNeutron_Star_Interior_Composition_Explorer%3E&format=text%2Fturtle
It is also visible as space in the URL in the HTML view: e.g. https://dbpedia.org/page/Neutron_Star_Interior_Composition_Explorer
I didn't check the latest dumps
