The "0️⃣" emote or "Digit Zero" emote is a symbol used to represent the number zero in digital communication, such as text messages, social media posts, and online chats. It consists of the digit 0 followed by a combining character called a variation selector, which modifies the appearance of the preceding character. The emote is often used in combination with other numbers or symbols to represent numerical values, such as phone numbers, addresses, and passwords.
