The glyph is not a composition. It has no designated width in East Asian texts. In bidirectional text it is written from left to right. When changing direction it is not mirrored. The word that U+028B forms with similar adjacent characters prevents a line break inside it. The glyph can be confused with one other glyph.
The Wikipedia has the following information about this codepoint:
The letter V with hook (Majuscule: Ʋ, minuscule: ʋ) is a letter of the Latin alphabet, based on an italic form of V, although it more closely resembles U. It is used in the orthographies of some African languages such as Ewe, and Shona from 1931 to 1955 to write [β], like the pronunciation of ⟨v⟩ in "van" using both lips. In Mossi (Mooré) it is used to write [ʊ], like the pronunciation of ⟨oo⟩ in "foot". In Kabiye and Ikposso it is used to write [u] (with retracted tongue root), like the pronunciation of ⟨oo⟩ in "food". It is also used in the North American language Choctaw to write [ə], a schwa, like the pronunciation of ⟨a⟩ in "again".
Its lowercase form, [ʋ], is used in the International Phonetic Alphabet for a labiodental approximant.
Its Unicode code points are U+01B2 and U+028B, respectively.
