You must make use of the returned value to slice your wstring. Something 
like this (not compiled):

    auto actualLength = GetUserNameW(lpwszUsername.ptr, &dUsername2);
    auto userName = lpwszUsername[0..actualLength];

Otherwise, D knows that lpwszUsername is a 254-char string and will try 
to print all of it.
