UTF-8输入有问题 [英] Trouble with UTF-8 input

问题描述

我的简单代码输出时日语字符没有问题，但是由于某种原因，它不能正确输入，是否缺少某些东西?

My simple code has no trouble with Japanese characters when outputting, but for some reason it doesn't take input properly, is it lacking something?

int main()
{
    _setmode(_fileno(stdout), _O_U16TEXT);
    SetConsoleCP(CP_UTF8);

std::wstring s = L"こんにちは, 世界!\nHello, World!";
std::wcout << s << endl;
std::wstring test;

getline(wcin, test);

std::wstring test2 = test;
std::wcout << test2 << endl;

std::wstring test3 = test2;
std::wcout << test3 << endl;
std::wcout << "Press ENTER to exit.";
std::wcout << "\n";
cin.get();
return 0;
}

推荐答案

此代码在Windows 10命令提示符下对我有用.关于 _O _ 标志的解释不多...

This code worked for me in the Windows 10 command prompt. There isn't much explanation about the _O_ flags...

#include <fcntl.h>
#include <io.h>
#include <string>
#include <iostream>

using namespace std;

int main()
{
    _setmode(_fileno(stdout),  _O_U16TEXT); // _O_WTEXT also worked
    _setmode(_fileno(stdin), _O_WTEXT);   // only _O_WTEXT worked

    wstring s = L"こんにちは, 世界!\nHello, World!";
    wcout << s << endl;

    wstring test;
    getline(wcin, test);
    wcout << test << endl;
    return 0;
}

输出:

C:\>test
こんにちは, 世界!
Hello, World!
你好马克！                << input line
你好马克！
