So far as I can tell, this method cannot return nil (well, unless somebody subverts things) and yet two senders try to handle the result being nil.

EncodedCharSet class>scanSelectorAt: and CompoundTextConvertor>nextPutValue:toStream:withShiftSequenceIfNeededForLeadingChar:

If the intent was that something ought to sometimes happen that actually can't, maybe the code needs checking, just in case. All the other senders rely on the result being non-nil.
