Iota Symbol context note

Iota is the ninth letter of the Greek alphabet. In a character-reference page, its safest scope is code-point identity, lowercase-versus-uppercase form, and differentiation from Latin i and dotless ı. A formula that uses ι for an inclusion map, index, or other object must define that assignment locally; the character itself does not carry one permanent mathematical operation. Search, sorting, and copy workflows should preserve Greek script rather than silently normalizing the glyph to a Latin letter.
