VC中GBK与UTF8字符串的转换

1. void ConvertGBKToUtf8(CString& strGBK) {
2. int len=MultiByteToWideChar(CP_ACP, 0, (LPCTSTR)strGBK, -1, NULL,0);
3. unsigned short * wszUtf8 = new unsigned short[len+1];
4. memset(wszUtf8, 0, len * 2 + 2);
5. MultiByteToWideChar(CP_ACP, 0, (LPCTSTR)strGBK, -1, wszUtf8, len);
6. len = WideCharToMultiByte(CP_UTF8, 0, wszUtf8, -1, NULL, 0, NULL, NULL);
7. char *szUtf8=new char[len + 1];
8. memset(szUtf8, 0, len + 1);
9. WideCharToMultiByte (CP_UTF8, 0, wszUtf8, -1, szUtf8, len, NULL,NULL);
10. strGBK = szUtf8;
11. delete[] szUtf8;
12. delete[] wszUtf8;
13. }
