Does the program work correctly in Debug mode, but doesn't work in release mode?

Question

C++ / C#

Hello everyone, the problem is this: when you compile the code in the debug profile, it works fine, but the text is not displayed in the release profile, but it does the main thing (changes the title of the console).
What to do?
Here is the code:

#include "stdafx.h"

wchar_t OriginalTitle[5000];
wchar_t MyTitle[5000] = L"Супир тайтэль (я нассаль на двигатэль)";

int main(void)
{
  _wsetlocale(LC_ALL, L"ru_RU.UTF-8");
  setlocale(LC_ALL, "ru_RU.UTF-8");
  GetConsoleOriginalTitleW(OriginalTitle, 5000);
  wprintf(L"Я получил оригинальный тайтл!\nВот: '%s'\n\n", OriginalTitle);
  SetConsoleTitleW(MyTitle);
  wprintf(L"Я сменил оригинальный тайтл на: '%s'!\n", MyTitle);
  system("pause");
}

Answer 1

_wsetlocale(LC_ALL, L"Russian");
setlocale(LC_ALL, "Russian");

And it worked.)
