N-Triples is designed for *test cases*. It was never intended for large-scale machine-to-machine communication. It just happens to also work quite well for that.

As long as both vendors have the new feature switched off by default in their new versions, the additional cost is *zero*. \u escapes won't be removed from the N-Triples format. Vendors who want to maximize compatibility will *accept* UTF-8 encoded N-Triples, but will continue to *emit* \u-escaped N-Triples by default for the next couple of years.

We've got twelve billion triples sitting on a nice little cluster in DERI. I'm not interested in laptops.

Off the top of my head, I can't think of any format defined in the last decade that explicitly forbids the use of UTF-8 like N-Triples does. (I'm sure there are some, but it doesn't appear to be common.) In a world where UTF-16 and UTF-8 increasingly become universal, one actually has to do extra work to transmit plain US-ASCII. I'd really prefer an outcome where steps are taken towards removing that extra burden.

Best,
