SPARQL - Special characters   

Hi Pedro. If you have a literal value you can enclose it in quotes, this query reports no syntax errors for me:

PREFIX db: <http://dbpedia.org/resource/>
SELECT * WHERE {
"db:Orange_(fruit)" ?pf1 db:Fruit
}

Actually, I would think that this should work: http://dbpedia.org/resource/Orange_%28fruit%29
But apparently '%' isn't accepted either: 37000 Error SP030: SPARQL compiler, line 0: Invalid character in SPARQL expression at '%'

Hi Pedro. I'm not sure if it's working, because I can't get it to return any data, but I think the correct syntax is to put angle brackets around the resource:

PREFIX db: <http://dbpedia.org/resource/>
SELECT * WHERE {
<db:Orange_(fruit)> ?pf1 db:Fruit
}

When I use the above there are no errors, but all that appears on the results page is the column header pf1.

--edit Using the SPARQL Explorer I generated this example, which would imply a query like this is the correct form:

PREFIX db: <http://dbpedia.org/resource/>
SELECT * WHERE {
<db:Orange_%28fruit%29> ?pf1 db:Fruit
}

Still no results for me, though.
