能否支持linux

[ayakasuki]

如题，因为本身自己有linux的服务器并且比较轻便一些

现在支持了，就是字符串处理有亿点问题

现在支持了，就是字符串处理有亿点问题

参考一下，昨天调过了没问题。

代码：

#include <iostream>
#include <vector>
#include <string>
#include <locale>
#include <iconv.h>

std::wstring utf8_to_utf16le(const std::string& utf8_str) {
    iconv_t conv = iconv_open("UTF-16LE", "UTF-8");
    if (conv == (iconv_t)-1) {
        perror("iconv_open");
        return L"";
    }

    size_t in_bytes_left = utf8_str.size();
    size_t out_bytes_left = in_bytes_left * sizeof(wchar_t);
    std::vector<char> outbuf(out_bytes_left, 0);

    char* in_buf = const_cast<char*>(utf8_str.data());
    char* out_ptr = outbuf.data();

    if (iconv(conv, &in_buf, &in_bytes_left, &out_ptr, &out_bytes_left) == (size_t)-1) {
        perror("iconv");
        iconv_close(conv);
        return L"";
    }

    iconv_close(conv);
    std::wstring utf16_str(reinterpret_cast<wchar_t*>(outbuf.data()), outbuf.size() / sizeof(wchar_t));
    return utf16_str;
}

std::string utf16le_to_utf8(const std::wstring& utf16_str) {
    iconv_t conv = iconv_open("UTF-8", "UTF-16LE");
    if (conv == (iconv_t)-1) {
        perror("iconv_open");
        return "";
    }

    size_t in_bytes_left = utf16_str.size() * sizeof(wchar_t);
    size_t out_bytes_left = in_bytes_left;
    std::vector<char> outbuf(out_bytes_left, 0);

    char* in_buf = reinterpret_cast<char*>(const_cast<wchar_t*>(utf16_str.data()));
    char* out_ptr = outbuf.data();

    if (iconv(conv, &in_buf, &in_bytes_left, &out_ptr, &out_bytes_left) == (size_t)-1) {
        perror("iconv");
        iconv_close(conv);
        return "";
    }

    iconv_close(conv);
    return std::string(outbuf.data());
}

测试代码：

static void set_locale()
{
    std::locale::global(std::locale(""));
   // std::locale::global(std::locale("zh_CN.UTF-8")); 

}

int main() {

    set_locale();
    std::cout << u8"测试中文输出显示" << "\n";
    std::string utf8_string = u8"你好，世界！";
    std::wstring utf16le_string = utf8_to_utf16le(utf8_string);

    std::string converted_back_to_utf8 = utf16le_to_utf8(utf16le_string);

    std::cout << "Original UTF-8 string: " << utf8_string.c_str() << std::endl;
    std::cout << "Converted to UTF-16 LE and back to UTF-8: " << converted_back_to_utf8.c_str() << std::endl;

    return 0;
}
