Answer 1

Did you look at the data on line 190 of https://www.googleapis.com/freebase/v1/rdf/m/02h40lc ?

ns:common.topic.alias    "Ingl\xeas"@pt;

It's not valid N3. http://www.w3.org/TeamSubmission/n3/#escaping

You'll need to pre-process the data into a valid form if you want RDF parsers to be able to deal with it. (And, of course, you should report the bug to Google as well).
