This character is a Otro símbolo 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 is written from left to right. When changing direction it is not mirrored. The word that U+1D15C forms with similar adjacent characters prevents a line break inside it.
El Wikipedia tiene la siguiente información acerca de este punto de código:
In music, a double whole note (American), breve (British) or double note lasts two times as long as a whole note (or semibreve). It is the second-longest note value still in use in modern music notation. The longest notated note is the longa, which could be double or triple the length of a breve, although its use is most commonly found in early music. The longest notated note (though now obsolete) is the maxima.
