The insane part is trying to solve the problems created by homoglyphs in post-assignment.

What's the need to allow both `O` and `0` on a plate if it's supposed to be hard to tell apart anyway? Say there was some reason to want to both characters, why allow assigning a new plate which would match with an existing assignment? It's just a loss of time, resources, and safety for both law enforcement and everyone else to allow duplicate matches to be a possibility.
