Re: Wide_[Wide_]Character

It is RM 3.5.2 (3/2) But the RM just defines that Ada uses 
ISO-10646:2003 (32-bit).  The 32-bit came from the Standard package and 
other place which also defines the ISO-10646:2003 as 32-bits. The unicode 
version is 4.0 came from the web page which states "The character 
repertoire corresponds to ISO/IEC 10646:2003."  Which is owned by an 
agency that deals will the unicode standard. And on other locations and at 
that site it states that for evey "ISO/IEC" there is one, not multiple 
corresponding unicode version.

Also, unicode version 4.0 suport all pervious version with some changes 
listed on the web page.  Just like unicode version 5.0 supports version 4.0, 
4.0.1, 4.1.0 and etc with some other changes.

Now, Ada does it does not define how to use all of its the character set. 
That's up to the programmers that is using Ada.
