There's actually no 8-bit ASCII. People sometimes use that to mean

The drivers may well just be returning whatever bytes were sent over
the wire. Now, in any *sane* protocol, the protocol docs would define
what encoding the bytes over the wire are in, but it took a very long
time for people to realize this, so it wouldn't shock me if 802.11b
doesn't specify. Then you'd basically have to do experiments with
common access points to see how they encode things, then add
appropriate heuristics to NetworkManager.
