Reading from file with special characters into a string-CodePudding

I have an c program that should read a text from a file named "Pontaje.txt" and store it into a string. The problem is that in that file is an special character and the program can't use it properly.

Pontaje.txt

Note that "—"(is a special character) is not "-"(from the keyboard)

main.cpp

#include <iostream>
#include <string>
#include <fstream>

int main()
{
    std::ifstream test("Pontaje.txt");
    std::string test2;
    std::getline(test, test2);
    std::cout << test2;
}

Output:

∩╗┐[604] Dumy | 17501 ΓÇö Today at 12:01 AM

How can I assign in test2 that line properly?

Note that I've tried using std::wifstream , std::wstring and std::wcout but i get the same result

CodePudding user response：

ΓÇö is a tell-tale sign: it's three characters instead of one. That happens when the input is encoded using UTF-8 (a multi-byte character set) but the output is done with a single-byte character set. I can't directly eyeball what character set contains all of ΓÇö, though.

IOW the problem is not the input or the output, but the assumption that they're using the same character set. And std::string makes no assumptions at all about character sets.
