I think the "other excludes sign information" wording makes this sound like a
portability diagnostic. I was going for wording that retains the same
"seriousness" for the plain char versus signed/unsigned char case as for the
signed char versus unsigned char case.
Would "where one is of the unique plain char type and the other is not" work?
