我知道如何使用但是它特定于Windows,是否存在仅使用stdio或iostream来完成相同功能的跨平台C ++函数?
but it is Windows-specific, is there a cross-platform C++ function that does the same thing, using only stdio or iostream?
推荐答案
我建议使用 utf8-cpp库,它很简单,而且涉及到utf8字符串.
i suggest using utf8-cpp library it is simple and to the point when it comes to utf8 strings .
此代码读取UTF-8文件并创建每行的utf16版本,然后转换回utf-8
this code reads UTF-8 file and creates a utf16 version of each line, then converts back to utf-8
#include <fstream>
#include <iostream>
#include <string>
#include <vector>
#include "utf8.h"
using namespace std;
int main(int argc, char** argv)
{
if (argc != 2) {
cout << "\nUsage: docsample filename\n";
return 0;
}
const char* test_file_path = argv[1];
// Open the test file (contains UTF-8 encoded text)
ifstream fs8(test_file_path);
if (!fs8.is_open()) {
cout << "Could not open " << test_file_path << endl;
return 0;
}
string line;
while (getline(fs8, line)) {
// Convert the line to utf-16
vector<unsigned short> utf16line;
utf8::utf8to16(line.begin(), end_it, back_inserter(utf16line));
// And back to utf-8
string utf8line;
utf8::utf16to8(utf16line.begin(), utf16line.end(), back_inserter(utf8line));
}
return 0;
}
