Are there Unicode symbols for parenthesis generator symbols?

Hi Folks,

In the book Parsing Techniques the authors use a less than symbol with a dot tucked inside for the open parenthesis and a greater than symbol with a dot tucked insider for the close parenthesis. Also, they use an equal sign with a dot over it. You can see the 3 symbols here:

Are there Unicode symbols for the 3 symbols?
