title: Where is hex code of the "EOF" character?
body: <p>As far as know in the end of all files, specially text files, there is a Hex code for <strong>EOF</strong> or <strong>NULL</strong> character. And when we want to write a program and read the contents of a text file, we send the read function until we receive that EOF hexcode.</p>
  <p>My question : I downloaded some tools to see a hex view of a text file. but I can't see any hex code for <strong>EOF</strong>(End Of File/NULL) or <strong>EOT</strong>(End Of Text)</p>
