We don't determine the behavior from Unicode.  We use the Unicode data
to implement the behavior we consider useful.

Whatever additional behavior and nuances the users want, we can
implement it regardless of the Unicode data we use for the basic
folding (once we figure out what is it that they want and how to
implement that best).  There's no dichotomy here.
