You don't have to use the C library to see that there is a problem. Just
use the utilities that come with Windows. I just tried this on Windows 7:
 
  C:\>copy con file
  asdf
  

Now the file has no Ctrl-Z in it. It is 6 bytes long "asdf\r\n".
So far so good, right?

But now use a binary editor to insert a ctrl-Z as the first character
of the file:
 
  C:\> type file

nothing!

  C:\> copy file con

nothing!

But if we load the file in Notepad, we see everything and the Ctrl-Z shows as a
graphical character.

These clowns still haven't figured out a consistent representation of text
files that holds across their operating system.

But then, look, the idiotic drive letter is still there, so what do you expect.
