Unicode character into CEdit - c++

Question

I'm generating a custom CEdit control that allows me to set some different colors on it. It works fine until I generate on control with the style ES_PASSWORD.
In these cases, I cannot find the way to write the character I want (big black dot). Here are some codes I've tried:
First option:
int lenght = text.GetLength();
text = "";
for (int i = 0; i < lenght; i++) text.AppendChar('\u25CF');
Second option:
int lenght = text.GetLength();
text = "";
for (int i = 0; i < lenght; i++) text.Append("\u25CF");
Third option:
int lenght = text.GetLength();
text = "";
for (int i = 0; i < lenght; i++) text.AppendChar((char)"\u25CF");
I don't understand why the control doesn't display the correct character. It only displays this: <. What am I doing wrong?
UPDATE
Here is the OnPaint() method I'm using:
void CEasyEdit::OnPaint()
{
// I generate all requiered objects.
CPaintDC dc(this);
CRect ClientRect;
GetClientRect(&ClientRect);
// I define which colors I want to use.
SetDefaultColors();
// I paint the background and its borders.
CBrush brush(m_clrBack);
dc.FillRect(ClientRect, &brush);
CRect border_rect;
this->GetClientRect(border_rect);
border_rect.InflateRect(1, 1);
dc.Draw3dRect(border_rect, m_clrBack, m_clrBack);
border_rect.InflateRect(1, 1);
dc.Draw3dRect(border_rect, m_clrBack, m_clrBack);
// I redefine the size of the rect.
CRect textRect(ClientRect);
textRect.DeflateRect(4, 1);
// I define the text to draw.
CString text;
GetWindowText(text);
// If it displays a password, I change its characters.
if (GetStyle() & ES_PASSWORD)
{
// I redefine the text to show.
int lenght = text.GetLength();
wchar_t f = '1060';
text = "";
for (int i = 0; i < lenght; i++) text.Append("\u0053");
}
// I draw the text.
dc.SetTextColor(m_clrText);
dc.SetBkColor(m_clrBack);
dc.SelectObject(GetFont());
dc.DrawText(text, -1, textRect, GetStyle());
}

I was looking up CEdit::GetPasswordChar and I notice it says:
If you create the edit control with the ES_PASSWORD style, the DLL
that supports the control determines the default password character.
The manifest or the InitCommonControlsEx method determines which DLL
supports the edit control. If user32.dll supports the edit control,
the default password character is ASTERISK ('*', U+002A). If
comctl32.dll version 6 supports the edit control, the default
character is BLACK CIRCLE ('●', U+25CF). For more information about
which DLL and version supports the common controls, see Shell and
Common Controls Versions.
That said, why can't you just use CEdit::SetPasswordChar where it states:
Specifies the character to be displayed in place of the character
typed by the user. If ch is 0, the actual characters typed by the user
are displayed.
