This character is a Other Letter and is mainly used in the Pahawh Hmong script. The character is also known as day.
The glyph is not a composition. It has no designated width in East Asian texts. In bidirectional text it is written from left to right. When changing direction it is not mirrored. The word that U+16B68 forms with similar adjacent characters prevents a line break inside it.
