Lets see, K is for kosher, Circled D is for Kosher dairy and a Circled U is for Orthodox Kosher. Look at some cereal boxes.....
Learn something new everyday... Noticing little cirlced "P" on some of my cd's. Cool.

A circled "S" is a service mark, meaning the government or whatnot is using the property of another for Official use.
I made a very simple font, shift P creates a circled P character. Thats the only character in the font. So load it to your system, then select that font to type a circled P ( shift P), then select your usual text for the rest of the legal line. Very simple. Created With helvetica regular type face. May not be suitable for very small white text, but should work fine for down to 6pt black overprint. Gimme some feedback and I can add to it. Should get you by in a pinch.
