Reading files as characters
If I choose any file and change extension to txt, 
I can read it in notepad. If I change extension back 
to original, a file is still valid. 
However, if i copy/paste txt into another notepad window 
and save it with original extension, file endsup corrupt. 
Why? What happens in a copy/paste process? How to avoid it?
