windows中文操作系统下，vs的c++项目默认编码是GB2312
python默认是utf-8编码
最好在c++程序顶上加：
#pragma execution_character_set("GB2312")
c++中的字符串一定就是gbk编码
传入python前要做编码转换
准备一个gbk转utf8的函数，如下（网上的）：

string GbkToUtf8(const char* src_str) { int len = MultiByteToWideChar(CP_ACP, 0, src_str, -1, NULL, 0); wchar_t* wstr = new wchar_t[len + 1]; memset(wstr, 0, len + 1); MultiByteToWideChar(CP_ACP, 0, src_str, -1, wstr, len); len = WideCharToMultiByte(CP_UTF8, 0, wstr, -1, NULL, 0, NULL, NULL); char* str = new char[len + 1]; memset(str, 0, len + 1); WideCharToMultiByte(CP_UTF8, 0, wstr, -1, str, len, NULL, NULL); string strTemp = str; if (wstr) delete[] wstr; if (str) delete[] str; return strTemp; } |
