I've implemented a work-around which was suggested via e-mail by several
people: sustitute the null-character between '^' and [0-3]. Because it
has zero-width, it will not be displayed. In my own application, because
the string is returned from an editText item to my function parser, I must
also remove the null-character after the dialog is dismissed.
