ansi utf8与unicode互转函数

乱码伤不起啊。。。。

下面是转换代码。。。

inline wstring utf8ToUnicode(string str)

{

//UTF8 to Unicode

size_t wcsLen = ::MultiByteToWideChar(CP_UTF8, NULL, str.c_str(), str.length(), NULL, 0);

//分配空间要给''留个空间，MultiByteToWideChar不会给''空间

wchar_t* wszString = new wchar_t[wcsLen + 1];

memset(wszString, 0, sizeof(wchar_t)*(wcsLen + 1));

//转换

::MultiByteToWideChar(CP_UTF8, NULL, str.c_str(), str.length(), wszString, wcsLen);

wstring wstr= wszString;

delete wszString;

return wstr;

}

inline string unicode2utf8(wstring wstr)

{

int len; www.2cto.com

len = WideCharToMultiByte(CP_UTF8, 0, wstr.c_str(), -1, NULL, 0, NULL, NULL);

char *szUtf8=new char[len*2 + 2];

memset(szUtf8, 0, len * 2 + 2);

WideCharToMultiByte (CP_UTF8, 0, (LPCWSTR)wstr.c_str(), -1, szUtf8, len, NULL,NULL);

string str= szUtf8;

delete szUtf8;

return str;

}
