这篇文章主要介绍了c++调用python中文乱码问题,本文通过实例代码给大家介绍的非常详细，对大家的学习或工作具有一定的参考借鉴价值，需要的朋友可以参考下

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;

									   }

示例性代码：

									#pragma execution_character_set("GB2312")

									#include <stdlib.h>

									#include <Windows.h>   

									#include <iostream>

									#include <Python.h>

									#include <string>

									#include <atlstr.h>

									using namespace System;

									using namespace System::Runtime::InteropServices;

									using namespace System::Collections::Generic;

									using namespace System::Diagnostics;

									using namespace System::Threading;

									using namespace std;

									int main()

									{  

									  const char* name = "东方红1号";

									  Py_Initialize();//初始化python

									  PyRun_SimpleString("import sys");

									  PyRun_SimpleString("sys.path.append('./')");

									  PyObject* pModule = PyImport_ImportModule("hello");

									  PyObject* pFunc1 = PyObject_GetAttrString(pModule, "sayhello");   

									  PyObject* pArgs = PyTuple_New(1);

									  PyObject* pV1 = Py_BuildValue("s", GbkToUtf8(name).c_str());      

									  PyTuple_SetItem(pArgs, 0, pV1);

									  PyObject* result = PyObject_CallObject(pFunc1, pArgs);

									  Py_Finalize();

									  return 0;
