the letters used on some european number plates for cars make the two symbols look different. this is done by making the zero rather egg-shaped and the o more circular, but most of all by cutting open the zero on the upper right side, so the circle is not closed any more (as in ). the style of letters chosen is called "" (abbr.: "fe schrift"), meaning "script which is harder to falsify". but those used in the united kingdom do not make the letter o and the number 0 look different from each other, because there can never be any mistake if the letters are correctly spaced.
