Hi there,
> apache-jena-fuseki-3.5.0
That's quite old - the current version is 3.17.0
Upgrading would be a good idea just in case.
Are there any messages in the server log file?
It is going to be difficult to pin down an encoding issue (if that is
what it is) because by the time we get this email, it has been
encoded/decoded so many times it may have changed the data.
What displays correctly one way may actually be different bytes, but it
is hidden by display reversing the mis-encoding. This is especailly
true for data displayed in web-browsers.
It is worth executing the queries from the command line with Fuseki running.
Looking at the UTF-8, the first and third queries look right.

Hello, when I query in Fuseki like this:
PREFIX : <http://dsc.nlp-bigdatalab.org:8086/>
SELECT * WHERE {
?s ?p ?o.
} #query1
It can return the many results ,one of the results is:
:口腔毛滴虫病 rdf:type :症状
when I query like this:
PREFIX : <http://dsc.nlp-bigdatalab.org:8086/>
SELECT * WHERE {
:口腔毛滴虫病 rdf:type ?o.
} #query2
it can return the results:
:症状
(That does not show a prefix for rdf: presumably the real query has that
PREFIX in it?)
Could you try the query with
<http://dsc.nlp-bigdatalab.org:8086/口腔毛滴虫病>
This eliminates one step - the prefix to URI conversion.
but when I query like this:
PREFIX : <http://dsc.nlp-bigdatalab.org:8086/>
SELECT * WHERE {
?s rdf:type :症状.
} #query3
it returns:
No data available in table
it confused me again
is this the problem related to the OWL data in
..\jena\apache-jena-fuseki-3.5.0\run\databases?
or RDF data in ..\jena\tdb
I would certainly check the data by dumping the database.
That is especially the the encoding of the URI <http://dsc.nlp-
bigdatalab.org:8086/口腔毛滴虫病>
look forward and thanks for your reply
