VS中utf8转换为unicode

 

C++函数

1. char* UTF82Char(const char* szU8)
2. {
3.     int wcsLen = MultiByteToWideChar(CP_UTF8, NULL, szU8, (int)strlen(szU8), NULL, 0);
4.     wchar_t* wszString = new wchar_t[wcsLen + 1];
5.     MultiByteToWideChar(CP_UTF8, NULL, szU8, (int)strlen(szU8), wszString, wcsLen);
6.     wszString[wcsLen] = '\0';
7.     int len = WideCharToMultiByte(CP_ACP, 0, wszString, (int)wcslen(wszString), NULL, 0, NULL, NULL);
8.     char* c = new char[len + 1];
9.     WideCharToMultiByte(CP_ACP, 0, wszString, (int)wcslen(wszString), c, len, NULL, NULL);
10.     c[len] = '\0';
11.     delete[] wszString;
12.     return c;
13. }
