i use fuseki with the SPARQL update "INSERT DATA {...}" command, send as
a HTTP POST to a fuseki server.
this works very well except when a triple contains in a literal a BOM
(65279) character. Then the confirmation is still positiv (204) but the
triples are NOT inserted.
the issue is not that the request with the BOM is ignored - this is
probably a good thing, but that a 204 confirmation is produced; some
information pointing to a syntax error in the SPARQL request or similar
is necessary.
i cannot see if the request arrives at the fuseki server ok - is there a
flag i can set when starting the fuseki server to show the request as it
is received? i can only see that the server is receiving the POST.
here the protocol of the sender:
callHTTP5 :
request POST http://xxxxt:3030/march25/update HTTP/1.1
Accept: */*
Content-Length: 586
Content-Type: application/sparql-update
requestbody INSERT DATA { GRAPH <http://gerastree.at/g12>
{<http://gerastree.at/waterhouse-kw#>
<http://gerastree.at/lit_2014#titel> " the BOM "@xx .
....
} }
callHTTP5 result is is Right HTTP/1.1 204 No Content
Date: Sun, 26 Mar 2017 10:32:08 GMT
Fuseki-Request-ID: 39
Connection: close
the literal is "\65279 the BOM " - if i remove the BOM mark, the
contents are stored, but the response from the server is exactly the same!
please produce an appropriate error message!
