U+2136 "ℶ" Bet Symbol Unicode Character
Unicode Version 17.0
U+2136 "ℶ" Bet Symbol is a typographic representation of the second letter of the Hebrew alphabet, aleph-bet, and is used primarily in mathematical and linguistic contexts to denote the second transfinite cardinal number in set theory, following the aleph numbers introduced by Georg Cantor. In notation, it specifically represents the cardinality of the continuum or other large infinite sets within the beth sequence, where beth‑zero equals aleph‑null and beth‑one equals the cardinality of the real numbers. Unlike the aleph symbol, which has a distinct Unicode code point, the bet symbol appears in mathematical works to clarify which infinite cardinal hierarchy is being referenced. It is also sometimes used in Jewish textual studies to represent the letter bet, though in modern digital text it may require specific fonts for proper rendering.
