!keywords Wide Character and Wide String
!discussion ASIS does not provide the capability for wide characters
and wide string support, because ASIS.Character and ASIS.String are
based upon Standard.Character and Standard.String respectively.  The
current ASIS specification makes no provision for ISO/IEC 10646-1:1993
characters or strings. which precludes an application that utilizes
these data types for either as source text, comments or expressions.
The current implementation will fail, when an ASIS application has
source that contains wide characters or wide strings.

!resolution  Accepted.

!Notes

Commentary in Section 3 was changed to read:

     "The ASIS interface uses string parameters for many 
     procedure and function calls. Wide_String is used to 
     convey ASIS environment information. Program_Text, a 
     subtype of Wide_String is used to convey program text. 
     The type String is not used in the ASIS interface. 
     Neither the Ada types Character nor Wide_Character are 
     used in the ASIS interface."

A new subtype was added:

        subtype Program_Text is Wide_String;

Program_Text was defined in Section 3.14 so as not to cause 
a renumbering of sections. This is also a good logical place 
for Program_Text as the subtype is closely associated with 
Package Asis.Text, numbered as Clause 20 towards the end.

All the overloading between the previous String and 
Wide_String subprograms has been eliminated.

The following functions and parameters now use Wide_String
as types of their parameters or return values:

	6.1 function ASIS_Version
