U+1091F Phoenician Word Separator

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.
