录音版权所有 ℗

The Latin capital letter 「P」 in a circle actually represents the copyright symbol used in the music industry. This symbol indicates a melody, composition, song, or other work which is protected by copyright. The letter 「P」 is used in the symbol for a reason; it refers to the English word 「phonogram.」

Usually, next to the Sound Recording Copyright symbol you can also see the year of the work's release and the owner's identifier. The unfilled circle with a 「P」 belongs to 字母式符号  2100–214F .

符号 「录音版权所有」 包含在 「字母式符号」 块的 「字母符號」 子块中，并在1993年作为Unicode版本1.1的一部分获得批准。
