-  This file contains the implementation of the WideString type,

-  WideString is defined as a 'silent' pwidechar :
-  a pwidechar that points to :
-
-  @-8  : SizeInt for reference count;
-  @-4  : SizeInt for size; size=number of bytes, not the number of chars. Divide or multiply
-         with sizeof(WideChar) to convert. This is needed to be compatible with Delphi and
-         Windows COM BSTR.
-  @    : String + Terminating #0;
-  Pwidechar(Widestring) is a valid typecast.
-  So WS[i] is converted to the address @WS+i-1.
-
-  Constants should be assigned a reference count of -1
-  Meaning that they can't be disposed of.
