This character is a Lowercase Letter and is mainly used in the Latin 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+A772 forms with similar adjacent characters prevents a line break inside it.
The Wikipedia has the following information about this codepoint:
Scribal abbreviations, or sigla (singular: siglum), are abbreviations used by ancient and medieval scribes writing in various languages, including Latin, Greek, Old English and Old Norse.
In modern manuscript editing (substantive and mechanical) sigla are the symbols used to indicate the source manuscript (e.g. variations in text between different such manuscripts).
