Turtle serializing creates invalid PNames #1661
Description
Consider following triple from DBPedia serialized as .ttl:
test.ttl
@prefix ns1: <http://dbpedia.org/property/> .
<http://dbpedia.org/resource/Maine_Mendoza> ns2:spouse(s)_ "Nate Winchester 2013-Present"@en .
It is not possible to parse this triple due to the brackets in ns2:spouses(s)_ in a .ttl file. However, there is no such problem for an .nt file.
Code to parse the test.ttl file with the triple inside.
from rdflib import Graph
g = Graph()
g.parse(test.ttl)
