This character is a Other Symbol and is commonly used, that is, in no specific script. The character is also known as semibreve.
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+1D15D forms with similar adjacent characters prevents a line break inside it.
The Wikipedia has the following information about this codepoint:
A whole note (American) or semibreve (British) in musical notation is a single note equivalent to or lasting as long as two half notes or four quarter notes.
