The Wikipedia has the following information about this codepoint:
Bet, Beth, Beh, or Vet is the second letter of the Semitic abjads, including Arabic bāʾب, Aramaic bēṯ 𐡁, Hebrew bētב, Phoenician bēt 𐤁, and Syriac bēṯ ܒ. Its sound value is the voiced bilabial stop ⟨b⟩ or the voiced labiodental fricative ⟨v⟩.
The letter's name means "house" in various Semitic languages (Arabic bayt, Akkadian bītu, bētu, Hebrew: bayīṯ, Phoenician bēt etc.; ultimately all from Proto-Semitic *bayt-), and appears to derive from an Egyptian hieroglyph of a house by acrophony.
The Phoenician letter gave rise to, among others, the Greek beta (Β, β), Latin B (B, b) and Cyrillic Be (Б, б) and Ve (В, в).
