This is an excellent point that I have not thought of. The natural solution
is through the use of a lookup table. But, in general, this requires TWO
tables: uppercase and lowercase. However, a single CHANGE_CASE table is
sufficient if it is guaranteed that lower_case(x) >= upper_case(x). Does
anyone know if this assumption is valid?
