This character is a Other Punctuation and is mainly used in the Arabic script.
The glyph is not a composition. It has no designated width in East Asian texts. In bidirectional text it is written as Arabic letter from right to left. When changing direction it is not mirrored. The word that U+066D 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 Arabic star is a punctuation mark added to Unicode 1.1 because the asterisk (*) might appear similar to a Star of David in its six-lobed form (✻).
The Arabic star is given a distinct character in Unicode, U+066D٭ARABIC FIVE POINTED STAR (the note ‘appearance rather variable’ was added in Unicode 5.1), in the range Arabic punctuation.
