Or we could follow vehicle VIN regulations and prohibit the use of the letters 'O' and 'I' completely, then for sure they are 0's and 1's.
I always assumed that this is why Siemens use Q for outputs, as the German translation starts with A.
British number plates on cars used to follow an alphabetical pattern and they omitted some letters such as I, O and U from the prefix for this reason.
