Remove Dot from String

Trying to remove a Dot from a String i´m experiencing a problem. With different Chars such as "," or "-" its working properly but the Dot won´t disappear.

Got a TextBox with the Name nr_tb. I Input Hello.World and my MessageBox outputs the same. Changing the Dot in the Replace function with a "," works.

Not working:

string line; 
private void nr_tb_TextChanged(object sender, TextChangedEventArgs e)
   {

            line = nr_tb.Text.Replace(".","");
            MessageBox.Show(line);
    }

Working:

string line;
private void nr_tb_TextChanged(object sender, TextChangedEventArgs e)
    {

            line = nr_tb.Text.Replace(",","");
            MessageBox.Show(line);
    }

It might be another character that seems like a DOT. Char code of DOT is 46 so if you get this char code in your string you can easily Replace(".", ""); it.

This method show each char code of a string:

    private static string DotRemover(string temp)
    {
        string _Result = string.Empty;
        foreach (byte a in Encoding.UTF8.GetBytes(temp.ToCharArray()))
        {
            _Result += a.ToString() + Environment.NewLine;
        }
        return _Result;
    }

OR

you can replace everything that look likes a DOT :

public static string CleanNumb(string numb) 
{
    foreach (char c in ".,'´")
       numb = numb.Replace(c, ' ');

    return numb.Replace(" ", "");
}
