There is a strange problem: insert the data encoded as UTF-8:
INSERT DATA { <http://onto.pro/Test> <http://www.w3.org/2000/01/rdf-schema#label> "Проверка" }
then extract them:
SELECT * WHERE { <http://onto.pro/Test> <http://www.w3.org/2000/01/rdf-schema#label> ?a }
and the encoding is broken:
{ "head": { "vars": [ "a" ] } , "results": { "bindings": [ { "a": { "type": "literal" , "value": "????????" } } ] } }
As can be seen, instead of "Проверка" returned "????????". The problem occurs suddenly and disappears after restart Fuseki. Where to dig?
