U+07F9 NKo Exclamation Mark

Die Wikipedia hat die folgende Information zu diesem Codepunkt:

N'Ko (N'Ko: ߒߞߏ) is an alphabetic script devised by Solomana Kanté in 1949, as a modern writing system for the Manding languages of West Africa. The term N'Ko, which means I say in all Manding languages, is also used for the Manding literary standard written in the N'Ko 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. N'Ko tones are marked as diacritics, in a similar manner to the marking of some vowels in Arabic.
