B with stroke (majuscule: Ƀ, minuscule: ƀ) is a letter of the Latin alphabet, formed from B with the addition of a bar, which can be through either the ascender or the bowl. It is used as a phonetic symbol to represent to transcribe the sound [β].[1]

⟨Ƀ⟩ is also a letter of the alphabets of the Rade, Jarai and Katu languages of Vietnam, and is used in standardized texts in Old Saxon as well as in reconstructed forms of Proto-Germanic.

Unicode[edit]

The minuscule form has been present in Unicode since version 1 (1991), but the majuscule form was not added until version 5 (2006).

Bitcoin[edit]

Before the introduction of the Unicode symbol, ₿, for the popular cryptocurrency Bitcoin, the symbol for the Thai baht, ฿ (U+0E3F), had sometimes been used. However, this caused possible confusion with the baht while Ƀ had no other uses related to currency. Therefore, Ƀ had been proposed as a substitute.[2][3]
