This character is a Nonspacing Mark and is mainly used in the Hebrew script.
The glyph is not a composition. It has no designated width in East Asian texts. In bidirectional text it acts as Nonspacing Mark. When changing direction it is not mirrored. U+05BB prohibits a line break before it.
The Wikipedia has the following information about this codepoint:
Kubutz or qubbutz (modern Hebrew: קֻבּוּץ; IPA:[kuˈbuts], formerly קִבּוּץ, qibbūṣ) and shuruk (Hebrew: שׁוּרוּק, IPA:[ʃuˈʁuk], also known as shuruq) are two Hebrew niqqud vowel signs that represent the sound [u]. In an alternative, Ashkenazi naming, the kubutz (three diagonal dots) is called "shuruk" and shuruk is called "melopum" (מלאפום).
