I am trying to create a custom MessageBox form. I want to display in a richtextbox greek characters but i get ????. The code to call the custom form:

 string msg = "Greek: αβγδ NotGreek:abcd";
                    using (MsgForm frm = new MsgForm("Caption", msg))
                    {

I found a solution. I wrote the greek chars in wordpad, saved the file in rtf format and open it with notepad. Doing so i managed to write a replace function for the Greek chars:

private void Form1_Load(object sender, EventArgs e)
        {
            this.Text = _caption;
            Replace();
            richTextBox1.Rtf = @"{
tf1\ansi\ansicpg1253 " + _text + "}";
        }

 private void Replace()
        {
            _text = _text.Replace("α", "\'e1");
            _text = _text.Replace("β", "\'e2");
            _text = _text.Replace("γ", "\'e3");
            _text = _text.Replace("δ", "\'e4");
            _text = _text.Replace("ε", "\'e5");
            _text = _text.Replace("ζ", "\'e6");
            _text = _text.Replace("η", "\'e7");
            _text = _text.Replace("θ", "\'e8");
            _text = _text.Replace("ι", "\'e9");
            _text = _text.Replace("κ", "\'ea");
            _text = _text.Replace("λ", "\'eb");
            _text = _text.Replace("μ", "\'ec");
            _text = _text.Replace("ν", "\'ed");
            _text = _text.Replace("ξ", "\'ee");
            _text = _text.Replace("ο", "\'ef");
            _text = _text.Replace("π", "\'f0");
            _text = _text.Replace("ρ", "\'f1");
            _text = _text.Replace("ς", "\'f2");
            _text = _text.Replace("σ", "\'f3");
            _text = _text.Replace("τ", "\'f4");
            _text = _text.Replace("υ", "\'f5");
            _text = _text.Replace("φ", "\'f6");
            _text = _text.Replace("χ", "\'f7");
            _text = _text.Replace("ψ", "\'f8");
            _text = _text.Replace("ω", "\'f9");

            _text = _text.Replace("Α", "\'c1");
            _text = _text.Replace("Β", "\'c2");
            _text = _text.Replace("Γ", "\'c3");
            _text = _text.Replace("Δ", "\'c4");
            _text = _text.Replace("Ε", "\'c5");
            _text = _text.Replace("Ζ", "\'c6");
            _text = _text.Replace("Η", "\'c7");
            _text = _text.Replace("Θ", "\'c8");
            _text = _text.Replace("Ι", "\'c9");
            _text = _text.Replace("Κ", "\'ca");
            _text = _text.Replace("Λ", "\'cb");
            _text = _text.Replace("Μ", "\'cc");
            _text = _text.Replace("Ν", "\'cd");
            _text = _text.Replace("Ξ", "\'ce");
            _text = _text.Replace("Ο", "\'cf");
            _text = _text.Replace("Π", "\'d0");
            _text = _text.Replace("Ρ", "\'d1");
            _text = _text.Replace("Σ", "\'d3");
            _text = _text.Replace("Τ", "\'d4");
            _text = _text.Replace("Υ", "\'d5");
            _text = _text.Replace("Φ", "\'d6");
            _text = _text.Replace("Χ", "\'d7");
            _text = _text.Replace("Ψ", "\'d8");
            _text = _text.Replace("Ω", "\'d9");

            _text = _text.Replace("ά", "\'dc");
            _text = _text.Replace("έ", "\'dd");
            _text = _text.Replace("ή", "\'de");
            _text = _text.Replace("ί", "\'df");
            _text = _text.Replace("ό", "\'fc");
            _text = _text.Replace("ύ", "\'fd");
            _text = _text.Replace("ώ", "\'fe");

            _text = _text.Replace("ϋ", "\'fb");
            _text = _text.Replace("ϊ", "\'fa");
            _text = _text.Replace("ΰ", "\'e0");
            _text = _text.Replace("ΐ", "\'c0");
        }
