Saw a car with license plate "4 GLD ★" which makes me wonder in the US (a) whether white space is significant, and (b) what other characters outside [0-9A-F] are allowed.

The answers will vary by state. California: dmv.ca.gov/wasapp/ipp2/initP… has some info.

I didn't notice what state the plate with star in it was. For California looks like space is significant, but also you can't choose zero?
