It may not be what you are looking for but it is **exactly** what you
asked for!

If I'd said

  function to_integer (c : character) return integer is
  begin
    return integer'value (string'(1 .. 1 => c));
  end to_integer;

would it be clearer?

You could try compiling and running my example, I assure you it works.
