I use IRIs in my RDF and fct to browse and do content negotiation, e.g. for `text/turtle`. However, there is an issue with inconsistent handling of unicode characters in `Location:`...
In develop/6, I have issue with loading xsd:double and xsd:decimal datatypes. When I load "50.08332824707031"^^xsd:double using SPARQL update, when I look at the value using fct or simply by querying,...
I am not sure whether or not this issue description is helpful, but today, our Virtuoso OS instance (f8aa59cd4ac29983f7afad7c32120e7f2552128b) crashed on general protection fault. This is everything I got from...
I have encountered a weird SPARQL query behavior. Commenting out some `OPTIONAL` clauses or adding a value to `VALUES` causes some relevant results to go missing. Tested on 3 instances,...
There is an issue with handling of Unicode characters with combination of SPARQL CONCAT and ENCODE_FOR_URI functions. When used like this: `BIND(CONCAT("https://c/é/", ENCODE_FOR_URI("Á")) as ?c)`, the resulting literal is `https://c/\u00E9/\u00C3\u0081%00`...
In f8aa59cd4ac29983f7afad7c32120e7f2552128b when I run `rdf_loader_run();` on previously created nquads dumps using [`dump_nquads`](http://vos.openlinksw.com/owiki/wiki/VOS/VirtRDFDumpNQuad), I get a crash: `GPF: vec.c:1189 extending dc past max batch size`. Originally, I tried with 7...
```sparql PREFIX xsd: SELECT * WHERE { BIND(NOW() as ?Now) BIND(DATATYPE(?Now) as ?Nowdt) BIND(STR(NOW()) as ?strNow) BIND(DATATYPE(?strNow) as ?strNowdt) BIND("2021-02-01" as ?datestr) BIND(DATATYPE(?datestr) as ?datestrdt) BIND(SUBSTR(?strNow,1,10) as ?substr) BIND(DATATYPE(?substr) as...
After update to 357d021429b1073e4d26b02007634e374f3e9d7a I started experiencing: ``` Virtuoso 42000 Error D1CT0: Hash dictionary memory pool is full, 200048640 exceeded 200000000 bytes ``` error when querying the SPARQL endpoint. This...
On [this endpoint](https://slovník.gov.cz/sparql) when I execute this query: ```sparql PREFIX rdfs: ASK { rdfs:subClassOf+ } ``` I get `false`. Indeed, in the data, there is no such property path. However,...
See [this instance](https://slovník.gov.cz/fct/) of FCT and try to search for "částka". All IRI links and some labels have mangled unicode characters.
