vc utf8与gb2312互相转换.

 

网上找到的版本大都是用CString转换的那个.估计是在vc6代写的东西.根本用不了.不过本人也是懒人.不想费那个事.这里找到了另一个版本.其实应该叫做c++ utf8与gb2312互相转换才对. //UTF-8到GB2312的转换 char* U2G(const char* utf8) { int len = MultiByteToWideChar(CP_UTF8, 0, utf8, -1, NULL, 0); wchar_t* wstr = new wchar_t[len+1]; memset(wstr, 0, len+1); MultiByteToWideChar(CP_UTF8, 0, utf8, -1, wstr, len); len = WideCharToMultiByte(CP_ACP, 0, wstr, -1, NULL, 0, NULL, NULL); char* str = new char[len+1]; memset(str, 0, len+1); WideCharToMultiByte(CP_ACP, 0, wstr, -1, str, len, NULL, NULL); if(wstr) delete[] wstr; return str; } //GB2312到UTF-8的转换 char* G2U(const char* gb2312) { int len = MultiByteToWideChar(CP_ACP, 0, gb2312, -1, NULL, 0); wchar_t* wstr = new wchar_t[len+1]; memset(wstr, 0, len+1); MultiByteToWideChar(CP_ACP, 0, gb2312, -1, wstr, len); len = WideCharToMultiByte(CP_UTF8, 0, wstr, -1, NULL, 0, NULL, NULL); char* str = new char[len+1]; memset(str, 0, len+1); WideCharToMultiByte(CP_UTF8, 0, wstr, -1, str, len, NULL, NULL); if(wstr) delete[] wstr; return str; } 无论是GB2312到UTF-8的转换，还是UTF-8到GB2312的转换，都需要注意的是在使用字符串后，需要删除字符串指针；这是因为以上两个方法返回的是字符串指针，如果没有删除将会内存泄漏，可别说我没提醒你哦。
