Right: to handle this, we need to distinguish characters that are
lower-case without an uppercase variant from characters which are
neither lowercase nor uppercase.

We could do that by saying that the upcase table should return nil or -1
for ß, to indicate that the upcase version is "missing".  But such
a change will probably require carefully revising "all" the code that
uses those tables.
