StringToUtf和UtfToString函数是转载至C++ 中文乱码的问题，该函数实现UTF-8和ANSI编码格式的转化，代码如下：
string UtfToString(string strValue)
{
int nwLen = ::MultiByteToWideChar(CP_ACP, 0, strValue.c_str(), -1, NULL, 0);
wchar_t* pwBuf = new wchar_t[nwLen + 1];//加上末尾'\0'
ZeroMemory(pwBuf, nwLen * 2 + 2);
::MultiByteToWideChar(CP_ACP, 0, strValue.c_str(), strValue.length(), pwBuf, nwLen);
int nLen = ::WideCharToMultiByte(CP_UTF8, 0, pwBuf, -1, NULL, NULL, NULL, NULL);
char* pBuf = new char[nLen + 1];
ZeroMemory(pBuf, nLen + 1);
::WideCharToMultiByte(CP_UTF8, 0, pwBuf, nwLen, pBuf, nLen, NULL, NULL);
std::string retStr(pBuf);
delete[]pwBuf;
delete[]pBuf;
pwBuf = NULL;
pBuf = NULL;
return retStr;
}
string StringToUtf(string strValue)
{
int nwLen = MultiByteToWideChar(CP_UTF8, 0, strValue.c_str(), -1, NULL, 0);
wchar_t* pwBuf = new wchar_t[nwLen + 1];//加上末尾'\0'
memset(pwBuf, 0, nwLen * 2 + 2);
MultiByteToWideChar(CP_UTF8, 0, strValue.c_str(), strValue.length(), pwBuf, nwLen);
int nLen = WideCharToMultiByte(CP_ACP, 0, pwBuf, -1, NULL, NULL, NULL, NULL);
char* pBuf = new char[nLen + 1];
memset(pBuf, 0, nLen + 1);
WideCharToMultiByte(CP_ACP, 0, pwBuf, nwLen, pBuf, nLen, NULL, NULL);
std::string retStr = pBuf;
delete[]pBuf;
delete[]pwBuf;
return retStr;
}
开始定义文件将所有文件直接定义为utf-8代签名即可。
