 * A further complication is that if letters and digits can appear in any order, it is dangerous to allow both the letter O and the digit 0 to be used. Even if the license plate uses distinguishable characters for the two, humans transcribing the plate may not know which symbol has which meaning, and the owner of plate EM6F9VO may get in trouble for something the owner of plate EM6F9V0 did. Other letter/number pairs, like I and 1, may be similarly problematic to a lesser degree.
