UTF-8 Validation with the Vector API (Performance)

[Paul Sandoz]

Hi August,

Thank you for bringing this to the list (I saw your messages on twitter and was gonna suggest you do just that but you got there before me).

This is exactly the kind of thing we are looking for to exercise the API and find performance issues. I shall take a closer look.

We have been methodically working through some performance issues based on other use cases, I think we will get there.

Paul,
