This character is a Other Letter and is mainly used in the Tagbanwa 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. The word that U+176F forms with similar adjacent characters prevents a line break inside it.
The Wikipedia has the following information about this codepoint:
Tagbanwa is one of the scripts indigenous to the Philippines, used by the Tagbanwa and the Palawan people as their ethnic writing system.
The Tagbanwa languages (Aborlan, Calamian and Central), which are Austronesian languages with about 8,000-25,000 total speakers in the central and northern regions of Palawan, are dying out as the younger generations of Tagbanwa are learning and using non-traditional languages such as Cuyonon and Tagalog, thus becoming less knowledgeable of their own indigenous cultural heritage. There are proposals to revive the script by teaching it in public and private schools with Tagbanwa populations.
