c/c++ 使用boost库实现的一个简单判断字符串编码的方法

自己记录一下，可能在某些情况下不能使用

#include <iostream>
#include <string.h>
#include <stdio.h>
#include <string>
#include "boost/locale.hpp"
#include "boost/program_options/detail/convert.hpp"
#include "boost/program_options/detail/utf8_codecvt_facet.hpp"
using namespace std;

static inline char* new_get_ascii_string(const string& name) {
    int i = 0, n;
    const char *s = name.c_str();
    char* buf = new char[strlen(s) * 4];
    char *p;
    p = buf;
    for (i = 0; i < strlen(s); i++) {
        n = sprintf(p, "%d", s[i]);
        p += n;
    }
    return buf;
}


int char_test(string test_string, string char_type ) {
    //获取原始字符串ascii码值的串
    char* raw_char = new_get_ascii_string(test_string);
    cout << "raw_char == " <<raw_char<< endl;
    //进行转码
    std::string conv(raw_char);
    std::string utf16 = boost::locale::conv::from_utf(test_string, char_type);
    cout << "conv string== " <<utf16<< endl;
    char* conv_result = new_get_ascii_string(utf16);
    cout << "conv_result == " <<conv_result<< endl;
    //进行对比
    if (!strcmp(raw_char,conv_result))
    {
        cout<<"it is same"<<endl;
    }
    else
    {
        cout<<"no equal"<<endl;
    }

    delete[] conv_result;
    delete[] raw_char;
}


int main(int argc, char *argv[]) {

    // 加入一个带汉字的字符串
    string test_string = "我i";
    string type = "gbk";
    char_test(test_string, type);
}
