Funny observation: This wouldn't happen in Norway...
Norwegian (like other Scandinavian languages) adds three extra letters (Æ, Ø Å) at the end of the alphabet, so the middle character is 'O' (which is easy to remember, as it looks the same from both sides...), and 'N' is in the lower half.
This obviously assumes that the rounding is bsed on the character number in the alphabet, counting from 'A' to the last character ('Å' in the Norwegian alphabet).
