This may be a silly question, but why aren't the character dependent 
packages generic?

It seems odd to have separate packages:

  Ada.Strings.Fixed;
  Ada.Strings.Wide_Fixed;
  Ada.Strings.Bounded;
  Ada.Strings.Wide_Bounded;
  Ada.Strings.Unbounded;
  Ada.Strings.Wide_Unbounded;
  Ada.Text_IO;
  Ada.Wide_Text_IO;

Instead of generic packages that use the character type as a parameter, with 
predefined instatiations for character and wide_character similar to what is 
done with numerics.  Perhaps something along the lines of:

  package Ada.Strings.Fixed is new Ada.Strings.String_Base( Character );
  package Ada.Strings.Wide_Fixed is new Ada.Strings.String_Base( 
Wide_Character );

and so on...

It seems like this would eliminate issues with different character sets, and 
avoid the need for a language revision when a 64 bit (or 128 bit) version of 
Unicode arrives.
