This character is a Other Letter and is mainly used in the Javanese script.
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. U+A9B1 forms an orthographic syllable in Brahmic scripts with similar characters, which prevents a line break inside it.
