U+20E3 "⃣" Combining Enclosing Keycap Unicode Character
Unicode Version 17.0
⃣
U+20E3 "⃣" Combining Enclosing Keycap is a combining diacritical mark designed to be placed after a preceding base character, typically a digit or letter, to visually enclose it within the familiar square outline of a telephone or computer keycap. This character does not appear as a standalone symbol but instead functions as a modifier, so when combined with a number like "1" it produces the widely recognized "1⃣" icon often used in emoji sequences or user interfaces. Its purpose is to support consistent, scalable rendering of keycap representations across different platforms and text systems, ensuring that any digit or symbol can be turned into a keycap graphic without needing a separate individual character for each combination.
