Help with SPARQL - referencing URI with special characters?

This relates to this question.
As part of my SPARQL query - I need to address the following resource:

Which contains round bracket characters. ‘(’ and ‘)’
I can do this using the ‘@base’ reference like this:

@base <http://dbpedia.org/resource/> .
@prefix  dbo: <http://dbpedia.org/ontology/> .
@prefix  dbp: <http://dbpedia.org/property/> .
@prefix  dbr: <http://dbpedia.org/resource/> .
@prefix : <http://dbpedia.org/resource/>.

SELECT *
WHERE
{
?person a dbo:Person.
FILTER(
        ?person IN (<Brian_Cox_(physicist)> )
)
} LIMIT 10

But is there a way of using a prefix instead?
The following gives an error:

SELECT *
WHERE
{
?person a dbo:Person.
FILTER(
        ?person IN ( dbr:Brian_Cox_(physicist) )
)
} LIMIT 10

Error:

Virtuoso 37000 Error SP030: SPARQL compiler, line 16: syntax error at 'physicist' before ')'

For contrast - the following works when the resource URL doesn’t contain any brackets:

@base <http://dbpedia.org/resource/> .
@prefix  dbo: <http://dbpedia.org/ontology/> .
@prefix  dbp: <http://dbpedia.org/property/> .
@prefix  dbr: <http://dbpedia.org/resource/> .
@prefix : <http://dbpedia.org/resource/>.

SELECT *
WHERE
{
?person a dbo:Person.
FILTER(
        ?person IN (dbr:Robin_Ince )
)
} LIMIT 10

But I can’t work out if there is a syntax that allows me to ‘escape’ the URI and use the prefix at the same time.

I have tried using URLEncoded characters like this:

@base <http://dbpedia.org/resource/> .
@prefix  dbo: <http://dbpedia.org/ontology/> .
@prefix  dbp: <http://dbpedia.org/property/> .
@prefix  dbr: <http://dbpedia.org/resource/> .
@prefix : <http://dbpedia.org/resource/>.

SELECT *
WHERE
{
?person a dbo:Person.
FILTER(
        ?person IN ( dbr:Brian_Cox_%28physicist%29)
)
} LIMIT 10

This avoids the SPARQL parse error - but doesn’t match anything.

OK - the following works - using '\ (backslash) character:

SELECT *
WHERE
{
?person a dbo:Person.
FILTER(
        ?person IN (
                dbr:Brian_Cox_\(physicist\)
        )
)
} LIMIT 10
