richedit with EM_SETCHARFORMAT SCF_SELECTION work until 256 ?

hello, im learning unicode richedit control like this

Code:

	CString data(_T("Data"));
	
	s_richedit.Append(data);  // s_richedit is CString control of rich edit

	CHARFORMAT2 cf;
	::memset(&cf, 0, sizeof(cf));
	cf.cbSize = sizeof(cf);
	cf.crTextColor = RGB(0,0,255);
	cf.dwMask = CFM_COLOR ;

	ctl_richedit.SetSel(ctl_richedit.GetTextLength(), ctl_richedit.GetTextLength() + data.GetLength()); //ctl_richedit is CRichEditCtrl of richedit

	::SendMessage(ctl_richedit.GetSafeHwnd(), EM_SETCHARFORMAT, SCF_SELECTION, (LPARAM) &cf);
	ctl_richedit.ReplaceSel(data);

actually that works, but when the size of richedit get around 256, the color back to BLACK
what's going on here? i had tried to replace

Code:

	ctl_richedit.SetSel(ctl_richedit.GetTextLength(), ctl_richedit.GetTextLength() + data.GetLength()); //ctl_richedit is CRichEditCtrl of richedit
with
	ctl_richedit.SetSel(ctl_richedit.GetTextLength(), 500); //ctl_richedit is CRichEditCtrl of richedit

nothing change
