This character is a Spacing Mark and is mainly used in the Hanunoo 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+1734 prohibits a line break before it. The glyph can be confused with one other glyph.
The Wikipedia has the following information about this codepoint:
Hanunoo (IPA:[hanunuʔɔ]), also rendered Hanunó'o, is one of the scripts indigenous to the Philippines and is used by the Mangyan peoples of southern Mindoro to write the Hanunó'o language.
It is an abugida descended from the Brahmic scripts, closely related to Sulat Tagalog, and is famous for being written vertical but written upward, rather than downward as nearly all other scripts (however, it is read horizontally left to right). It is usually written on bamboo by incising characters with a knife. Most known Hanunó'o inscriptions are relatively recent because of the perishable nature of bamboo. It is therefore difficult to trace the history of the script.
