display chinese caption on cbutton

Dear all,

    My computer system locale is Western English, and I want to display Chinese caption on the CButton as follows, however, it didn't work, do you know what's the problem?( I defined _UNICODE & UNICODE inside my project, and my resource file are already in CHINESE (PRC) format)


LPTSTR s_strRemarks=(LPTSTR)malloc((255)*sizeof(TCHAR));
s_strRemarks[0]=0x5c0f;  //Chinese character 1
s_strRemarks[1]=0x8003; //Chinese character 2
s_strRemarks[2]=0x8a66; //Chinese character 3
s_strRemarks[3]=0;

AfxMessageBox(s_strRemarks); //can display chinese character here inside the messagebox

///////////////Extra code for font///////////////
CFont m_font;
LOGFONT lf;
memset(&lf, 0, sizeof(LOGFONT));
lf.lfHeight = 10;    
lf.lfCharSet = CHINESEBIG5_CHARSET;
_tcscpy(lf.lfFaceName, _T("PMingLiU")); //chinese font
m_font.CreateFontIndirect(&lf);  
m_TestButton.SetFont(&m_font);
////////////

m_TestButton.SetWindowText(s_strRemarks);   //display garbage here no matter I have the "Extra code for font" or not.

delete[] s_strRemarks;
