U+1F53C · emoji since 2010
The upwards button is a triangle pointing up, the icon for scroll up or expand. It means higher, more above, and going up.
It marks dropdowns and increases, the simple control for heading further up the page.
In texting, 🔼 does not carry a widely used hidden or slang meaning, so you can usually take it at face value. People send it just as it looks, to add a little visual touch or set the mood of a message. Only a handful of emoji have a separate texting code, and 🔼 is not really one of them.
Its official Unicode name is the Upwards Button emoji. In everyday chat most people just call it the upwards button emoji or describe what it shows. Copy and paste it from the button at the top of this page.
The 🔼 leads off a short phrase, and the rest of the words are written in cipher, every letter disguised as another emoji. Tap decipher to reveal the whole line.
Or make your own cipher in the translator.
