*sigh* - Thanks Andy - turns out that both SPARQL queries in the RDFa
Test Suite start off with that BOM... which is why we were seeing those
Test Cases react in a similar manner.

We could remove it - but it's valid[1][2] UTF-8, isn't it? Technically,
we should be able to feed that to SPARQL and the engine should deal with
it, right?
