Based on documentation.  Yes, for every char.

No.

I am not ASSUMING that it is a doc bug.  It IS a doc bug.  The doc IS
obviously not matching the implementation.

> as opposed to a bug in the implementation?

Well, if you want to promote this report to a bug in implementation, I
have no reservations.  But the onus is in on YOU to argue on what counts
it can be deeemed as a bug in implementation.
