title: How can I cin and cout some unicode text?
body: <p>I ask a code snippet which cin a unicode text, concatenates another unicode one to the first unicode text and the cout the result.</p>
  
  <p>P.S. This code will help me to solve another bigger problem with unicode. But before the key thing is to accomplish what I ask.</p>
  
  <p>ADDED: BTW I can't write in the command line any unicode symbol when I run the executable file. How I should do that?</p>
