A.3.3 The Package Characters.Latin_1
The package Characters.Latin_1 declares constants
for characters in ISO 8859-1.
Reason: The constants for the ISO 646
characters could have been declared as renamings of objects declared
in package ASCII, as opposed to explicit constants. The main reason for
explicit constants was for consistency of style with the upper-half constants,
and to avoid emphasizing the package ASCII.
Static Semantics
The library package
Characters.Latin_1 has the following declaration:
package Ada.Characters.Latin_1
is
pragma Pure(Latin_1);
