This character is a Other Symbol and is commonly used, that is, in no specific script.
The glyph is not a composition. It has no designated width in East Asian texts. In bidirectional text it acts as Other Neutral. When changing direction it is not mirrored. The word that U+1D1EA forms with similar adjacent characters prevents a line break inside it.
The Wikipedia has the following information about this codepoint:
In the early 20th century, Iranian master musician Alinaghi Vaziri established the standard usage of this symbol in written music. It is used for notating many of the microtones found in traditional Persian music. A note so altered can be labeled as the note's letter, followed by "koron" (e.g., "B koron", "D koron", etc.). Character representation of this accidental symbol together with Sori (encoded as U+1D1E9 and U+1D1EA, respectively) microtones used in modern Iranian classical music were added to the Unicode standard in Version 14.0.0.
