// the RichTextBox will return a space.
// Alternatively, If you pass a unicode representation of zero (\u0?) it acts like a hard space and returns an ASCII
// representation (\'00). If you pass in the ASCII representation, it truncates the text.
// The following two lines replace hard spaces (ASCII) with the UNICODE represntation of Zero.
// Lastly, If you pass a unicode representation of one (\u1?) it acts like a hard space and returns an ASCII
// representation (\'01). If you pass in the ASCII representation, it keeps the ASCII representation.
