unicode转utf8当字符串内出现“踏”字的时候中文乱码

[长空行影]

以下是我用的转换函数 也都是在网上找到的和般情况下是没有问题的 ，可是如何字符串中存在“踏”字的时候就出现乱码，请各位看一下是怎么回事。。。
测试字符串： "防踩踏#19#res\Media\图片\JPG\防踩踏.jpg#JPG#5#1#1#0

void CFileServerDlg::ANSItoUTF8(CString &strAnsi)
{

USES_CONVERSION;
char * stransi = W2A(strAnsi);
//获取转换为宽字节后需要的缓冲区大小，创建宽字节缓冲区，936为简体中文GB2312代码页
UINT nLen = MultiByteToWideChar(CP_ACP, NULL, stransi, -1, NULL, NULL);
WCHAR *wszBuffer = new WCHAR[nLen + 1];
memset(wszBuffer, 0, nLen+1);
nLen = MultiByteToWideChar(CP_ACP, NULL, stransi, -1, wszBuffer, nLen);
wszBuffer[nLen] = 0;
//获取转为UTF8多字节后需要的缓冲区大小，创建多字节缓冲区
nLen = WideCharToMultiByte(CP_UTF8, NULL, wszBuffer, -1, NULL, NULL, NULL, NULL);
CHAR *szBuffer = new CHAR[nLen + 1];
memset(szBuffer, 0, nLen+1);
nLen = WideCharToMultiByte(CP_UTF8, NULL, wszBuffer, -1, szBuffer, nLen, NULL, NULL);
szBuffer[nLen] = 0;
string szbuffer = szBuffer;

strAnsi = szbuffer.c_str();
//内存清理
delete[]wszBuffer;
delete[]szBuffer;
}

CString CFileServerDlg::UnicodeToUtf8(CString Unicodestr)
{
wchar_t* unicode = Unicodestr.AllocSysString();
int len;
len = WideCharToMultiByte(CP_UTF8, 0, unicode, -1, NULL, 0, NULL, NULL);
char *szUtf8 = (char*)malloc(len + 1);
memset(szUtf8, 0, len + 1);
WideCharToMultiByte(CP_UTF8, 0, unicode, -1, szUtf8, len, NULL, NULL);
string result = szUtf8;
CString utfstr=CString(result.c_str());
free(szUtf8);
return utfstr;
}

一共就有90分，全用了 请高手看一下这个怎么破啊 。。

谢谢了啊 二楼给出解决办法的哥们。呵呵 原因找到了 是我后期的代码对数据的处理有问题与unicode-->unf8无关 后期处理是保存字符串到INI文件（以UTF8编码保存） 还是谢谢你。一会上分给你。

看到网上有很多问怎么存为utf8格式INI文的，下面我说一下我的具体操作步骤，望给遇到同样问题的人一个解决办法：
前提我的环境：unicode编码环境下 MFC程序

1、执行unicode 转 utf8

string CFileServerDlg::UnicodeToUtf8(CString Unicodestr)
{
wchar_t* unicode = Unicodestr.GetBuffer();
int len;
len = WideCharToMultiByte(CP_UTF8, 0, unicode, -1, NULL, 0, NULL, NULL);
char *szUtf8 = (char*)malloc(len + 1);
memset(szUtf8, 0, len + 1);
WideCharToMultiByte(CP_UTF8, 0, unicode, -1, szUtf8, len, NULL, NULL);
string result = szUtf8;
free(szUtf8);
return result;
}

2、用::WritePrivateProfileStringA(string.c_str()，string.c_str()，string.c_str()，string.c_str());
就可以了
注：在unicode环境下不要用WritePrivateProfileString 因为有的文字会出现乱码，我这次遇到的就是这样的问题。
