Well, it's ^D, but it's not an ascii character. It is defined as something 
which can never be read from a file. All ascii characters can be read. There 
is no character you can write to a file that will cause the file to stop 
being read because of end-of-file.

There is an ascii character 0x03 (end of text) and 0x04 (end of message) but 
those aren't the same as EOF

If you think about it, it's obvious: a binary file doesn't care about ascii 
encodings. The 127 characters in ascii can occur anywhere in - for example - 
a JPEG image. It would be disaster if that caused an end-of-file
