sendInput() can't work at chinese char?

[pclion]

i download a program:
static void SendString(LPCTSTR str)
{
INPUT inp[2];
memset(inp,0,sizeof(INPUT));
inp[0].type = INPUT_KEYBOARD;
inp[0].ki.dwFlags = KEYEVENTF_UNICODE; // to avoid shift, etc.
inp[1] = inp[0];
inp[1].ki.dwFlags |= KEYEVENTF_KEYUP;

for (LPCTSTR p=str; *p; p++) {
inp[0].ki.wScan = inp[1].ki.wScan = *p;
SendInput(2, inp, sizeof(INPUT));
}
}

it sending a english string, it working well.but i send a chinese char(unicode), i received chars such as a8 a2 3f. how do i send a chinese string?
