Note:
This changes SPARQL - specifically Syntax.ARQ.
Syntax.SPARQL_11 remains untouched.
Syntax.ARQ ("with extensions") is the default in jena-arq and also used in Fuseki.
See discussion:
SPARQL and Turtle differ in the way they handle \u and \U escapes.
In SPARQL, they can appear anywhere (even for special characters). ARQ does not support \U .
In Turtle, \u and \U can appear in strings and URIs, not in prefix names, and nowhere else. This is a better design.
