A.12.3 The Package Wide_Text_IO.Text_Streams
The package Wide_Text_IO.Text_Streams provides a 
function for treating a wide text file as a stream. 
Static Semantics
The library package 
Wide_Text_IO.Text_Streams has the following declaration: 
with Ada.Streams;
package Ada.Wide_Text_IO.Text_Streams 
is
   type Stream_Access 
is access all Streams.Root_Stream_Type'Class;
 
   function Stream (File : 
in File_Type) 
return Stream_Access;
end Ada.Wide_Text_IO.Text_Streams;
 
The Stream function has the same effect as the corresponding 
function in Streams.Stream_IO.
