--  This child package of Ada.Strings.Wide_Unbounded provides specialized

--  Wide_Text_IO routines that work directly with unbounded wide strings,

--  avoiding the inefficiencies of access via the standard interface, and also

--  taking direct advantage of the variable length semantics of these strings.

   --  extra copy of the argument is avoided.
