STD::string szDst；

wchar _ t wText[20]= { L " China China " }；

DWORD dwNum = WideCharToMultiByte(CP _ OEMCP，NULL，wText，- 1，NULL，0，NULL，FALSE)；

char * psText

psText = new char[dw num]；

WideCharToMultiByte (CP_OEMCP，NULL，wText，- 1，psText，dwNum，NULL，FALSE)；

szDst = psText

//Delete temporary variables

Delete [] pstext;

//output

cout & lt& ltszDst & lt& ltendl

Returns 0;
