疑问,求助大佬
一般用string存汉字没有问题,但为什么用string将汉字存入vector中最后会变成乱码呢?

先把它转成utf-8编码试试:
std::string string_To_UTF8(const std::string & str)
{
int nwLen = ::MultiByteToWideChar(CP_ACP, 0, str.c_str(), -1, NULL, 0);
wchar_t * pwBuf = new wchar_t;//一定要加1,不然会出现尾巴
ZeroMemory(pwBuf, nwLen * 2 + 2);
::MultiByteToWideChar(CP_ACP, 0, str.c_str(), str.length(), pwBuf, nwLen);
int nLen = ::WideCharToMultiByte(CP_UTF8, 0, pwBuf, -1, NULL, NULL, NULL, NULL);
char * pBuf = new char;
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;
}
用 wstring。
