UTF8 & GBK之间的转换

使用lua的时候,在lua中给字符串赋值的中文,但是在C中读出来的就是乱码,是因为在lua中使用的是UTF8编码,而在C(windows下面)中使用的是GBK编码,将UTF8转成GBK就可以了,下面的代码就是实现这一转换的

// 1、将GBK转换成UTF8string GBKToUTF8(const std::string& strGBK){ string strOutUTF8 = ""; WCHAR * str1; int n = MultiByteToWideChar(CP_ACP, 0, strGBK.c_str(), -1, NULL, 0); str1 = new WCHAR[n]; MultiByteToWideChar(CP_ACP, 0, strGBK.c_str(), -1, str1, n); n = WideCharToMultiByte(CP_UTF8, 0, str1, -1, NULL, 0, NULL, NULL); char * str2 = new char[n]; WideCharToMultiByte(CP_UTF8, 0, str1, -1, str2, n, NULL, NULL); strOutUTF8 = str2; delete[]str1; str1 = NULL; delete[]str2; str2 = NULL; return strOutUTF8;}// 2、将UTF8转换成GBKstring UTF8ToGBK(const std::string& strUTF8){ int len = MultiByteToWideChar(CP_UTF8, 0, strUTF8.c_str(), -1, NULL, 0); unsigned short * wszGBK = new unsigned short[len + 1]; memset(wszGBK, 0, len * 2 + 2); MultiByteToWideChar(CP_UTF8, 0, (LPCTSTR)strUTF8.c_str(), -1, wszGBK, len); len = WideCharToMultiByte(CP_ACP, 0, wszGBK, -1, NULL, 0, NULL, NULL); char *szGBK = new char[len + 1]; memset(szGBK, 0, len + 1); WideCharToMultiByte(CP_ACP,0, wszGBK, -1, szGBK, len, NULL, NULL); //strUTF8 = szGBK; std::string strTemp(szGBK); delete[]szGBK; delete[]wszGBK; return strTemp;}
