U+1D170 "𝅰" Musical Symbol Combining Flag-3 Unicode Character

U+1D170 "𝅰" Musical Symbol Combining Flag-3 is a combining mark used in Western musical notation to indicate that a note stem should be adorned with three small flags, typically applied to the stem of a note head to specify a rhythmic value of a 128th note or its equivalent in various compound meters. This symbol is part of the Musical Symbols block in Unicode and is designed to be placed after a note stem character, combining visually to extend the duration subdivision beyond the standard 64th note flag, thereby enabling precise notation of very fast or complex rhythmic passages. Its use is primarily relevant in engraved sheet music or academic contexts where high fidelity to traditional notation is required.
