从文件显示西里尔文 [英] Displaying cyrillic text from file

问题描述

好吧，我有一个西里尔字符的文件。我加载它，从它得到一个字符串，然后尝试使用sf :: Text显示它。这是我的代码看起来像：

Well, I have got a file with cyrillic characters. I am loading it, getting a string from it and then trying to display it with sf::Text. That's what my code looks like:

#include <iostream>
#include <SFML/Graphics.hpp>
#include <fstream>
#include <string>

using namespace std;

int main()
{
    sf::RenderWindow window(sf::VideoMode(800,600),"Learn me");
    sf::Text before;
    wifstream lvl;
    lvl.open("text.txt");
    sf::Font font;
    font.loadFromFile("CODE2000.ttf");
    before.setFont(font);
    before.setCharacterSize(20);
    before.setColor(sf::Color(150,150,150));
    wstring stri;
    getline(lvl,stri);
    before.setString(stri);
    while(window.isOpen()){
        sf::Event event;
        while(window.pollEvent(event)){
            switch(event.type){
        case sf::Event::Closed:
            window.close();
            }
        }

        window.clear();
        window.draw(before);
        window.display();
    }
    lvl.close();
    return 0;
}

但这只显示奇怪的字符。

but this does only display strange characters.

这一个正在工作：

#include <iostream>
#include <SFML/Graphics.hpp>
#include <fstream>
#include <string>
#include <algorithm>

using namespace std;

int main()
{
    sf::RenderWindow window(sf::VideoMode(800,600),"Learn me");
    sf::Text before;
    wifstream lvl;
    lvl.open("text.txt");
    sf::Font font;
    font.loadFromFile("CODE2000.ttf");
    before.setFont(font);
    before.setCharacterSize(20);
    before.setColor(sf::Color(150,150,150));
    wstring stri;
    getline(lvl,stri);
    sf::String text;
    text=sf::String::fromUtf8(begin(stri),end(stri));
    before.setString(text);
    while(window.isOpen()){
        sf::Event event;
        while(window.pollEvent(event)){
            switch(event.type){
            case sf::Event::Closed:
                window.close();
            }
        }

        window.clear();
        window.draw(before);
        window.display();
    }
    lvl.close();
    return 0;
}

推荐答案

C ++使用宽字符串（ std :: wstring ）代表UNICODE。这是不是 UTF-8。要从UTF-8编码文件读取 std :: wstring ，请阅读将Unicode UTF-8文件读入wstring 并使用第二个答案。

C++ uses wide strings (std::wstring) to represent UNICODE. This is not UTF-8. To read a std::wstring from an UTF-8 encoded file, please read Read Unicode UTF-8 file into wstring and use the second answer.

随着时间的推移，这将是一个告诉你使用这个功能：

In case the order changes over time, that would be the one that tells you to use this function:

#include <sstream>
#include <fstream>
#include <codecvt>

std::wstring readFile(const char* filename)
{
    std::wifstream wif(filename);
    wif.imbue(std::locale(std::locale::empty(), new std::codecvt_utf8<wchar_t>));
    std::wstringstream wss;
    wss << wif.rdbuf();
    return wss.str();
}

一旦您获得了有效的 std :: wstring 从您的文件，您应该能够使用它与SFML没有问题。

Once you have obtained a valid std::wstring from your file, you should be able to use it with SFML without problems.
