The Wikipedia has the following information about this codepoint:

In music notation, a sixty-fourth note (American), or hemidemisemiquaver or semidemisemiquaver (British) is a note played for half the duration of a thirty-second note (or demisemiquaver), hence the name. It first occurs in the late 17th century and, apart from rare occurrences of one-hundred-twenty-eighth notes, (semihemidemisemiquavers), it is the shortest value found in musical notation (Morehen 2001).

Sixty-fourth notes are notated with a filled-in oval note head and a straight note stem with four flags. The stem is drawn to the left of the note head going downward when the note is above or on the middle line of the staff. When the note head is below the middle line the stem is drawn to the right of the note head going upward. Multiple adjacent sixty-fourth notes may have the flags connected with a beam.

A similar, but rarely encountered symbol is the sixty-fourth rest (or hemidemisemiquaver rest, shown on the right of the image) which denotes silence for the same duration as a sixty-fourth note.

Notes shorter than a sixty-fourth note are very rarely used, though the hundred twenty-eighth note (otherwise known as the semihemidemisemiquaver or quasihemidemisemiquaver), and even shorter notes, are occasionally found.

The names of this note (and rest) vary greatly in European languages:

"Semifusa" derives from the mensural notation corresponding to the modern sixteenth note.
