TurtleTests/localName_with_non_leading_extras URI escape

Hello,

Why is the "." escaped as \u002e in

http://www.w3.org/2013/TurtleTests/localName_with_non_leading_extras.nt

My implementation does not escape this character since, even in the old
NTriples spec,

absoluteURI ::= ( character - ( '<' | '>' | space ) )+	 
character   ::= [#x20-#x7E] /* US-ASCII space to decimal 127 */

Which includes ".", #x2E.  Accordingly, my implementation does not
escape this character.  Should it?
