My finished version:

FUNCTION char_to_slv (c : CHARACTER) RETURN STD_LOGIC_VECTOR IS
    variable Return_Value : STD_LOGIC_VECTOR(7 downto 0);
BEGIN
    case c is
	when '0' =3D> Return_Value :=3D STD_LOGIC_VECTOR(TO_UNSIGNED(0,8));
	when '1' =3D> Return_Value :=3D STD_LOGIC_VECTOR(TO_UNSIGNED(1,8));
	when '2' =3D> Return_Value :=3D STD_LOGIC_VECTOR(TO_UNSIGNED(2,8));
	when '3' =3D> Return_Value :=3D STD_LOGIC_VECTOR(TO_UNSIGNED(3,8));
	when '4' =3D> Return_Value :=3D STD_LOGIC_VECTOR(TO_UNSIGNED(4,8));
	when '5' =3D> Return_Value :=3D STD_LOGIC_VECTOR(TO_UNSIGNED(5,8));
	when '6' =3D> Return_Value :=3D STD_LOGIC_VECTOR(TO_UNSIGNED(6,8));
	when '7' =3D> Return_Value :=3D STD_LOGIC_VECTOR(TO_UNSIGNED(7,8));
	when '8' =3D> Return_Value :=3D STD_LOGIC_VECTOR(TO_UNSIGNED(8,8));
	when '9' =3D> Return_Value :=3D STD_LOGIC_VECTOR(TO_UNSIGNED(9,8));
	when '-' =3D> Return_Value :=3D STD_LOGIC_VECTOR(TO_UNSIGNED(45,8));
	when others =3D> Return_Value :=3D (OTHERS =3D> '1');
   end case;

Later I will add the lowercase letters but this gets me through the
day.  Thanks for you help everyone.

Mike -- Your answers are always amazing to me.  You find super compact
ways of doing clever things.  I confess I don't understand your
version this time but as usual, I will synthesize it and look at the
RTL viewer to see how yours does the same thing as mine in a tenth the
number of lines!

Shannon
	return(Return_Value);

	END char_to_slv;
