Circled Latin Small Letter T

The Circled Latin Small Letter T at U+24E3 is a lowercase t enclosed in a circle, used as a ready-made label or marker rather than as an ordinary alphabetic letter. It belongs to the Enclosed Alphanumerics block, which contains letters and numbers precomposed with circles, parentheses, and similar enclosures for compact notation. In real use, ⓣ most often appears in lists, diagrams, forms, and educational material where circled letters distinguish steps, choices, map points, or keyed annotations. A worksheet might label subparts ⓐ through ⓣ, or a technical illustration might use ⓣ as a callout marker when plain letters would be too easy to miss. It is also used in decorative or stylized text online, especially in usernames, headings, badges, and social-media posts that imitate sticker-like lettering. Because it is a compatibility-style enclosed letter, it should not be treated as equivalent to a normal t in search, sorting, identifiers, or abbreviations unless software explicitly normalizes it.
