Why doesn't this simple program work? [duplicate]

Question

I'm trying to sort out everything concerning the way Unicode works in Windows console applications. Why doesn't this simple program work?

#include <iostream>

int wmain(int argc, const wchar_t* const argv[])
{
    for (int i = 1; i < argc; ++i)
        std::wcout << argv[i] << std::endl;

    return 0;
}

Compiled with

>cl /EHsc /D _UNICODE /D UNICODE /Zc:wchar_t test.cpp

the program produces

> test.exe 1 2 3 abc абв
1
2
3
abc

Where is the fifth argument? I have to mention that абв fits into both my GetACP() and GetConsoleCP() & GetConsoleOutputCP() code pages (1251, 866 & 866). It's interesting that the program works (in a way) with the characters outside of those code pages:

> test.exe Sæter
Sцter

But:

> test.exe абв Sæter

Answer 1

I think this is because wcout converts to narrow characters.

See this other question about this topic.

Another good link.
