This character is a Other Punctuation and is mainly used in the N’Ko 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. It will not end a sentence. U+07F8 prohibits a line break after it, and before it, too, if preceded by a number.
The Wikipedia has the following information about this codepoint:
NKo (ߒߞߏ), also spelled N'Ko, is an alphabetic script devised by Solomana Kanté in 1949, as a modern writing system for the Manding languages of West Africa. The term NKo, which means I say in all Manding languages, is also used for the Manding literary standard written in the NKo script.
The script has a few similarities to the Arabic script, notably its direction (right-to-left) and the letters that are connected at the base. Unlike Arabic, it is obligatory to mark both tone and vowels. NKo tones are marked as diacritics.
