Try:
<http://dbpedia.org/page/Orange_%28fruit%29>
1/ "(" and ")" aren't allowed in URIs, nor in prefixed names. Browsers
kindly encode them into %28 and %29
For example: go to
http://dbpedia.org/page/Orange_(fruit)
with Firefox and then cut and paste the contents of the URL bar into a
text editor. You get %28-%29 (in FF 3.6 at least)
2/ This is an encoding, not an escape sequence - the URIs really do have
"%-2-8" and "%-2-9" in them.
3/ SPARQL does not allow % in a prefixed name so you'll have to use
WHERE
{<http://dbpedia.org/page/Orange_%28fruit%29>
?p ?o . }
or
BASE <http://dbpedia.org/page/>
SELECT ?p ?o
WHERE { <Orange_%28fruit%29> ?p ?o . }
The fact that <http://dbpedia.org/page/Orange_(fruit)> works is more
luck than anything else :-)

Hi,
My question is straightforward, but I didn't find it through Google. Actually,
I ran into someone with the same problem, but there was no answer in the thread.
How should I escape things like the parenthesis in:
PREFIX dbpedia:<http://dbpedia.org/resource/>
SELECT ?p ?o
WHERE { dbpedia:Orange_(fruit) ?p ?o . }
(Gives error about "(" )
Note that the following does work:
SELECT ?p ?o
WHERE {<http://dbpedia.org/resource/Orange_(fruit)> ?p ?o . }
Thanks,

P.S. Thanks for the comments on my Union question, it really helped to clarify
the problem!
