title: UTF-8: How can the reader know how many bytes a character counts?
body: <p>UTF-8 can represent each character by one byte or more. Let's suppose that I have the following byte sequence:</p>
  
  <pre><code>48 65
  </code></pre>
  
  <p>How can I know if it's one character represented by <code>48</code> and another character represented by <code>65</code>, or it's ONE character represented by a combination of TWO bytes <code>48 65</code>?</p>
