title: wchar ends with single null byte or two of them?
body: <p>I just don't understand and can't find much info about wchar end.</p>
  
  <p>If it ends with single null byte, how it know it not string end yet, if something like that "009A" represent one of unicode symbols?</p>
  
  <p>If it ends with two null bytes? Well, I am not sure about it, need confirmation.</p>
