Posting here at Bilka's request.

If an order string isn't supplied for an entity, it is set to: . Where item is the item to place the entity.

When asked why the "z-" prefix is being appended, Bilka said "I do not know. All I know is that it's 10-year-old behaviour"

More info: It's noted on https://lua-api.factorio.com/latest/pro ... html#order and also somewhat needs me to finally check if https://wiki.factorio.com/Tutorial:Loca ... sed_String is completely correct.
