This character is a Other Punctuation and is mainly used in the Phoenician script.
The glyph is not a composition. It has no designated width in East Asian texts. In bidirectional text it acts as Other Neutral. When changing direction it is not mirrored. U+1091F offers a line break opportunity after its position.
The Wikipedia has the following information about this codepoint:
In punctuation, a word divider is a form of glyph which separates written words. In languages which use the Latin, Cyrillic, and Arabic alphabets, as well as other scripts of Europe and West Asia, the word divider is a blank space, or whitespace. This convention is spreading, along with other aspects of European punctuation, to Asia and Africa, where words are usually written without word separation.
In character encoding, word segmentation depends on which characters are defined as word dividers.
