Local names - non-alphanumeric characters

[schwarja]

Query:

PREFIX : <http://www.uochb.org/chebi/1.0/terms#>
SELECT DISTINCT ?S FROM <http://localhost:8890/chebi_db> WHERE
{
    ?X :chebi\=Name / :nameValue ?S.
}

Result:

Virtuoso 37000 Error SP030: SPARQL compiler, line 0: Bad character '\' (0x5c) in SPARQL expression at '\'

But according to SPARQL 1.1 domentation (http://www.w3.org/TR/sparql11-query/#prefNames):

SPARQL local names also allow the non-alphanumeric characters allowed in IRIs via backslash character escapes (e.g. ns:id\=123).

           ?s ?p ?o
           FILTER (?s=:Grimaldi_\(crater\))
       }
    }

Result:

"Virtuoso 37000 Error SP030: SPARQL compiler, line 0: Bad character '\\' (0x5c) in SPARQL expression at '\\'\n\nSPARQL query:\n\n [...]
