I agree with Jeremy.

For us, the lack of UTF-8 support is a serious impediment to using N-Triples as a bulk dump/restore format.

We use UTF-8 internally to hold RDF literals, as every other format is natively UTF-8, so the export to N-Triples requires a lot of unnecessary and inefficient escaping.
