What would be the purpose of encoding these? I can't think of any. They certainly don't need to be encoded as distinct characters to use in a Last Resort font.
I am certain more people want to interchange the LITTER DUDE than would want to interchange script block indicators.
(Ken suggested offline that this name might be better-received than the DO NOT LITTER SIGN....)
