The glyph is not a composition. Its width in East Asian texts is determined by its context. It can be displayed wide or narrow. In bidirectional text it is written from left to right. When changing direction it is not mirrored. The word that U+0432 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:
Ve (В в; italics: Вв) is a letter of the Cyrillic script. It commonly represents the voiced labiodental fricative /v/, like ⟨v⟩ in "vase". It can also represent /ʋ/
The capital letter Ve looks the same as the capital Latin letter B but is pronounced differently.
Ve is commonly romanized by the Latin letter V (as described by ISO 9), but sometimes the Latin letter W is used instead, such as in Polish, or by the German Duden transcription.
