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 is written from left to right. When changing direction it is not mirrored. The word that U+1D130 forms with similar adjacent characters prevents a line break inside it.
The Wikipedia has the following information about this codepoint:
In music, sharp β eqv. diΓ¨se (from French) or diesis (from Greek δίΡΟΞΉΟ) β means higher in pitch. The sharp symbol, β―, indicates that the note to which the symbol is applied is played one semitone higher. The opposite of sharp is flat, indicating a lowering of pitch. The β― symbol derives from a square form of the letter b (see History of notation of accidentals for more information).
