Linux readdir如何处理文件名编码

    }

    <span>struct dirent *entry;</span>
    while ((entry = readdir(dir)) != NULL) {
        // 将文件名从多字节字符串转换为宽字符字符串
        size_t len = mbstowcs(NULL, entry->d_name, 0) + 1;
        wchar_t *wname = malloc(len * sizeof(wchar_t));
        mbstowcs(wname, entry->d_name, len);

        // 将宽字符字符串转换回多字节字符串（UTF-8编码）
        char *utf8name = malloc(len * sizeof(char));
        wcstombs(utf8name, wname, len);

        free(wname);
        free(utf8name);
    }

    closedir(dir);
