The need to dual-declare is important to know but its not the question I asked.

Is there ever a real life scenario where a single physical text file uses one 
character encoding for one range of octets in the file and a different character 
encoding for a different range of octets in the file.

I'm not aware of any text editor that when asked to save a document to disk 
would not be using the same character encoding to write out the entire file.

So I would think it would be a very contrived situation for a text file to exist 
physically that isn't all one encoding.

And then the question is whether we would consider it valid for such a file to 
exist and that we would try to support it as a non-corrupted file.
