This simpler n3 file has the same issue:

<http://example.com/article1> <http://example.com/title> "this word is in
\u201cquotes\u201d".

The nt parser can read it, but n3 can't. I was using n3 format for relative 
urls.

Oops- n3 is supposed to have uppercase hex in \u and \U escapes, so this error 
is
correct. Although I wouldn't mind if we matched the cwm behavior and permitted 
it :)
