U+07EC NKo Combining Short Low Tone

U+07EC was added in Unicode version 5.0 in 2006. It belongs to the block U+07C0 to U+07FF NKo in the U+0000 to U+FFFF Basic Multilingual Plane.

This character is a Nonspacing Mark 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 Nonspacing Mark. When changing direction it is not mirrored. U+07EC prohibits a line break before it.

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.
