title: How can I convert char to byte?
body: <p>I have simple question.
  As we know that <code>Char</code> takes two bytes (16 bit), and <code>Byte</code> takes one byte(8 bits).
  But in many programming languages there is a function that converts <code>Char</code> to <code>Byte</code>. How it is possible to convert <code>Char</code> to <code>Byte</code> without losing anything?</p>
