There's also the worry that it could trigger falsely
on something that happened to look like \uxxxx but
didn't originate from the repr of a unicode char.

It can only ever be a heuristic, though, not an
exact solution, since there isn't enough information
left by the time it's a string to undo the escaping
correctly in all cases.

I'm currently thinking there are too many use cases
overloaded onto repr() at the moment.
