The Ø Convention

The slashed letter is the canonical spelling, and it is not decoration. It is a signature that survives being copied, printed, translated, and read by a stranger.

One character, held on purpose. The Ø marks the name of the Source and the name of the body, and a reader meeting it knows immediately that this is not ordinary text (ØNE, LIØNSBERG, Naming Forms).

Four things are said to be carried in it, and they are worth knowing whether or not one finds them persuasive: the empty seat beneath the layers from which the rest emerges (FSx); a visual mark of something set apart, recognisable across languages and ages; the zero point, the still centre from which the spiral opens (Sacred Geometry, The Fundamental Tone); and the eternal present, the only moment anything is ever actually lived (Nøw, Here and Nøw).

The practical half is tolerance. Both spellings refer to the same thing, both resolve, and neither breaks the other; older writing is not hunted down and corrected (Interoperability, Weave, don't delete, Minimum standards of interoperability). What is fixed is what goes into anything meant to last — what is printed, what is carried in the seed, what is meant to be remembered (The Golden Seed, Every Page Lives Within A Volume).

The cost is worth naming, since a convention that ignores its own cost is a preference. A non-ASCII character is harder to type, unreliable in some systems, awkward to search for, and invisible to anyone reading in a font that does not carry it — which is a real tax on a body that means to be reachable by everyone (Conditions of Acceptance, Universal-Accessing, The grandmother test). That the mark is kept anyway is a judgment that the signature is worth the friction, and it should be held as a judgment rather than as a law.
