What 🯄 means
Use the palette in modern text; on CPC, use BASIC’s character code.
Its source is byte 0xFC in the Amstrad CPC character set. The 1984 CPC464 manual describes a 256-character display set for text and graphics, called up by number; PRINT CHR$(252) displays this character in CPC BASIC, and the manual assigns it no separate meaning.
If someone sends 🯄 alone, treat it as a possible retro-computing reference only when the conversation supports that; otherwise ask what they meant. Its history by itself does not reveal whether they are confused or joking.
