How to display national characters in a Windows desktop app - c++

Question

A Windows C++ desktop application displays texts with Swedish national characters. I develop it in Visual Studio (VS), as a "C++ Windows Desktop" project. VS builds a basic application with many files: one .cpp file, two .ico files, three .h files, one .rc file, and some project files, so it is too much to present here, and I'm showing only the important parts.
In wWinMain, I added a console to display texts using cout.
AllocConsole();
SetConsoleOutputCP(1252);
FILE* stream;
freopen_s(&stream, "CONOUT$", "w", stdout);
I am trying several ways to display text in WndProc in response to the WM_PAINT signal.
case WM_PAINT:
{
PAINTSTRUCT ps;
HDC hdc = BeginPaint(hWnd, &ps);
RECT rec;
GetClientRect(hWnd, &rec);
if (FIRST)
{
FIRST = false;
// Test with const char* s
const char* t1 = "Test 1: const char* s";
DrawTextA(hdc, (LPCSTR)t1, (int)strlen(t1), &rec, DT_TOP | DT_LEFT);
cout << t1 << endl;
rec.top += 16;
const char* s = "abcdef ååääöö ÅÅÄÄÖÖ\n";
DrawTextA(hdc, (LPCSTR)s, (int)strlen(s), &rec, DT_TOP | DT_LEFT);
cout << s << endl;
rec.top += 16;
// Test with string text
const char* t2 = "Test 2 string text";
DrawTextA(hdc, (LPCSTR)t2, (int)strlen(t2), &rec, DT_TOP | DT_LEFT);
cout << t2 << endl;
rec.top += 16;
string text = "abcdef ååääöö ÅÅÄÄÖÖ\n";
DrawTextA(hdc, (LPCSTR)&text, (int)text.length(), &rec, DT_TOP | DT_LEFT);
cout << text << endl;
rec.top += 16;
// Test with text (const char*) & string
const char* t3 = "Test 3 (const char*)& \"..\"";
DrawTextA(hdc, (LPCSTR)t3, (int)strlen(t3), &rec, DT_TOP | DT_LEFT);
cout << t3 << endl;
rec.top += 16;
text = "abcdef ååääöö ÅÅÄÄÖÖ\n";
const char* t = (const char*)&text;
DrawTextA(hdc, (LPCSTR)t, (int)strlen(t), &rec, DT_TOP | DT_LEFT);
cout << t << endl;;
rec.top += 16;
// Test with wide string text
const char* t4 = "Test 4 wstring text";
DrawTextA(hdc, (LPCSTR)t4, (int)strlen(t4), &rec, DT_TOP | DT_LEFT);
cout << t4 << endl;
rec.top += 16;
wstring wtext = L"abcdef ååääöö ÅÅÄÄÖÖ\n";
DrawTextW(hdc, (LPCWSTR)&wtext, (int)wtext.length(), &rec, DT_TOP | DT_LEFT);
wcout << wtext << endl;
rec.top += 16;
}
EndPaint(hWnd, &ps);
}
break;
The meaning of this is to verify how national characters are displayed using text sources in const char*, string, wstring, and const char* created from a string. The output in the desktop client window and in the console is presented below.
The output is correct when DrawTextA displays text as const char*. However, the displayed text is distorted when DrawTextA shows text from a string or const char* created from a string. Also, using wstring didn't help.
In my application, I must be able to display texts kept in strings. I don't care much about the console output; it is only there to make the testing easier. What am I missing?
