A button (blood type) Emoji

Symbols

A bold, red square button featuring the uppercase letter A. It is styled to look like a physical plastic or rubber key, similar to those found on older gaming consoles or specialized industrial control panels.

Usage Context

While it is technically a blood type indicator, most users employ this to mean 'grade A,' a top-tier ranking, or as a shorthand for the word 'answer.' It is often used in combination with 🅱 to highlight a binary choice or to reference specific blood types in medical discussions.

History

This character was added to the Unicode standard in 2010. It stems from the common practice in Japan of displaying blood types on social media profiles and personal cards, as blood type personality theory is a staple of Japanese pop culture.
