It should be noted that the final design for UTF-8 was sketched out on a placemat by Rob Pike and Ken Thompson.

I wonder if that placemat still exists today. It would be such an important piece of computer history.

> It was so easy once we saw it that there was no reason to keep the placemat for notes, and we left it behind. Or maybe we did bring it back to the lab; I'm not sure. But it's gone now.
