title: Why is the character é encoded as 0xC3 0xA9 in UTF-8?
body: <p>If I write the character <code>é</code> to a file and I open it with an hexadecimal editor I can see the bytes 0xC3, 0xA9.</p>
  
  <p>From Wikipedia, the first byte it's called the leading byte and the second, the trailing byte. 0xC3 it's a metadata byte that means that the character it's encoded with 1 byte, 0xA9, but the unicode value for <code>é</code> is <a href="http://www.unicode.org/charts/PDF/U0080.pdf" rel="nofollow">0xE9</a>.</p>
  
  <p>I basically want to know why <code>é</code> it's encoded with a 0xA9 instead of 0xE9. How the text editors convert from 0xC3A9 to 0xE9? Any shift operation?</p>
