What ⧄ means
The character list cross-references them; they remain separate symbols.
⍁ is APL’s functional symbol “quad slash”; APL is a programming language. 〼 is the Japanese masu mark. Unicode’s character-name list calls it an informal abbreviation for the Japanese verb ending ます. Neither character is an alternate encoding of ⧄.
