To solve the ambiguity problem in 1-step castling (or in other castlings where the castling piece can also move multiple squares on its own, such as that silly 'guarding' of the Queen in Enhanced Omega Chess), the Diagram uses the tilde instead of the hyphen (or nothing) as connecting sign for indicating castlings, like K~d1. But I like to stick to conventional SAN where this is possible.
