Let's try again.
This declaration:
declare
type Byte is mod 2 ** Character'Size;
for Byte'Size use Character'Size;
function To_Byte is new Unchecked_Conversion (Character, Byte);
B : constant Byte := To_Byte ('A');
begin
should have the same efficiency as this declaration
declare
C : constant Character := 'A';
begin
