+//	WideAscii
+//	*********
+//	The class is only a collection of methods. It does not
+//	describe any instantiable object or variable!
+//
+//	The primary premise is that the most information in the
+//	internet protocols is represented as a sequence of 8 bit
+//	bytes and is usually encoded as ASCII. When compiling
+//	protocol modules for UNICODE variant, clashes easily occur
+//	when textual ASCII data is transferred between the protocol
+//	message and some generic field that has been declared without
+//	explicit 8/16 specification.
+//
+//	*NOTE*
+//		The implementation uses the generic Copy method of the
+//		standard descriptor to actually deal with the 8/16
+//		conversion. One could use the same in the code directly,
+//		but it would be hard to spot those locations. The use of
+//		this class documents the intentional conversions
+//
+//		In addition to current simple ASCII method, one could
+//		in future more complex transfers, such as UTF8.
