U+0805 Samaritan Letter Baa

The Wikipedia has the following information about this codepoint:

Waw (wāw "hook") is the sixth letter of the Semitic abjads, including Phoenician wāw 𐤅, Aramaic waw 𐡅, Hebrew vav ו, Syriac waw ܘ and Arabic wāw و (sixth in abjadi order; 27th in modern Arabic order).

It represents the consonant [w] in classical Hebrew, and [v] in modern Hebrew, as well as the vowels [u] and [o]. In text with niqqud, a dot is added to the left or on top of the letter to indicate, respectively, the two vowel pronunciations.

It is the origin of Greek Ϝ (digamma) and Υ (upsilon), Cyrillic У, Latin F and V and later Y, and the derived Latin- or Roman-alphabet letters U and W.
