Letterlike Symbols Unicode Block
Letterlike Symbols is a collection of typographic characters that visually resemble letters or letter combinations but serve distinct purposes, such as mathematical constants, units of measurement, or abbreviations derived from words. Examples include symbols like ℅ (care of), ℔ (pound), ™ (trademark), and ℮ (estimated sign), as well as stylized forms like ℽ (Greek gamma) or ℏ (reduced Planck constant). These glyphs are used where a standard Latin or Greek letter would be ambiguous or where a compact, conventional notation is preferred in scientific, commercial, and technical contexts. The set also includes archaic or specialized ligatures and script variants, bridging the gap between ordinary alphabetic text and more abstract notation systems.
