title: const char* to LPCWSTR in Qt
body: <p>I have faced a problem in Qt with error: cannot convert parameter 1 from 'const char *' to 'LPCWSTR'
  when calling: OutputDebugString( "wtf!" );</p>
  
  <p>In simple C++ project I've always been setting "Character Set" to "Not Set", but this time it doesn't work, the error keeps displaying all the time. I tried other possibilities like "Use multi-byte" but still no effect. What's going on?</p>
  
  <p>Thanks.</p>
