| -- OBJECTIVE: |
| -- Check that the functionality found in packages Ada.Strings.Wide_Maps, |
| -- Ada.Strings.Wide_Fixed, and Ada.Strings.Wide_Maps.Wide_Constants |
| -- is available and produces correct results. |
| -- |
| -- TEST DESCRIPTION: |
| -- This test validates the subprograms found in the various Wide_Map |
| -- and Wide_String packages. It is based on the tests CXA4024 and |
| -- CXA4026, which are tests for the complementary "non-wide" packages. |
| -- |
| -- The functions found in CXA4025_0 provide mapping capability, when |
| -- used in conjunction with Wide_Character_Mapping_Function objects. |
