    Description

      To load a file, Notepad maps a view of the file as a memory-mapped file and uses that as the source.
      		 
      The code figures out the encoding,
      		 
      performs a code page conversion to UTF-16LE if necessary,
      		 
      puts the result in a memory block,
      		 
      and then uses the EM_SET­HANDLE message to hand that entire block to the edit control.
