This character is a Other Letter and is mainly used in the Kawi 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+11F2B forms an orthographic syllable in Brahmic scripts with similar characters, which prevents a line break inside it.
The Wikipedia has the following information about this codepoint:
The Kawi script or the Old Javanese script (Indonesian: aksara kawi, aksara carakan kuna) is a Brahmic script found primarily in Java and used across much of Maritime Southeast Asia between the 8th century and the 16th century. The script is an abugida, meaning that characters are read with an inherent vowel. Diacritics are used, either to suppress the vowel and represent a pure consonant, or to represent other vowels.
