Telegram uses Apple emoji images instead of displaying platform-native emojis. These are updated to use the latest images from Apple, generally one month after public release on iOS.

Telegram allows custom stickers to be uploaded, and assigned to certain emojis. Stickers can be assigned a relevant emoji, to apear as an emoji tooltip. Voice calls are also secured by emoji.

As of September 2021, Telegram has a feature entitled Interactive Emoji. When a user sends one instance of a select emoji in any private chat, the emoji will display with a custom design which will display an animated fullscreen effect when tapped.

At present πŸŽ† Fireworks, πŸŽ‰ Party Popper, 🎈 Balloon, πŸ‘ Thumbs Up, πŸ’© Pile of Poo, and ❀️ Red Heart have Interactive Emoji support.

Telegram X, an alternative client from the same company, offers a choice of emoji sets such as the Google, Twitter, and Samsung sets.

It also offers popular Google blob emoji designs. The Apple set is the default, matching standard Telegram.
