Then it would be either a very boring document (containing almost only 
that same character) or it would be a very large document.

If you want space efficiency, the best thing to do is to use generic 
compression. Many generic compression methods are available, many of 
them are widely supported, and all of them will be dealing with your 
case in a very efficient way.

That's not agreed upon. I'd say that the general agreement is that the 
private ranges are of limited usefulness for some very limited use cases 
(such as designing encodings for new scripts).

Yes, but there are many other ways to do that besides Unicode. And for 
many purposes, these other ways are better suited.

Just a 'non sequitur'.
