I wonder why it allows NUL... I'm pretty sure JSON itself doesn't: you need to do a \u escape to do the control characters including NUL. It looks like that kind of escaping is just not supported at all in JSON Pointer. I kind of want to say that once you've noticed NUL is a problem enough to call it out the document, you should probably just ban it and pop in an escape to represent it.
