+I think it is one of general editing problem in RichTextBox. I created
+a simple repro code and steps:
+
+using System;
+using System.Windows.Forms;
+
+public class Test : Form
+{
+	public static void Main ()
+	{
+		Application.Run (new Test ());
+	}
+
+	public Test ()
+	{
+		this.Width = 100;
+		this.Height = 100;
+		RichTextBox rtb = new RichTextBox ();
+		rtb.Width = 40;
+		rtb.Height = 80;
+		Controls.Add (rtb);
+	}
+}
+
+Run this program, and try to enter "123 45". After the whitespace, it
+clips the text. And when you enter 5 (it would be dependent on the
+actual fonts you use), it will result in the same kind of error.
