最近编写程序，中文乱码问题让很多同学很头疼，那么今天黄老师来帮大家剖析一下：

以 “好人“  两个字为例：

 

等会我们使用代码跟踪内存，来查看字节的编码：

先上代码：

#include<stdio.h>
#include<stdlib.h> 
#include<windows.h>


char *   ConvertUTF8ToANSI(char *utf8 ) {
	int count = MultiByteToWideChar(CP_UTF8, 0, utf8, -1, NULL, 0);

	int len = sizeof(wchar_t)* (count + 1);
	wchar_t* wide = malloc(len);
	memset(wide, 0, len);

	MultiByteToWideChar(CP_UTF8, 0, utf8, -1, wide, count);

	count = WideCharToMultiByte(CP_ACP, 0, wide, -1, NULL, 0, NULL, NULL);
	
	int len2 = sizeof(char) *(count + 1);
	char* ansi =  malloc(len2 );
	memset(ansi, 0, len2);

	WideCharToMultiByte(CP_ACP, 0, wide, -1, ansi, count, NULL, NULL);
	 
	free(wide);
	return  ansi; 
}
