Where the 📐 emoji is used

The 📐 smiley copies in one tap and pastes into a chat as text, not as a picture: it is a Unicode symbol, so it works the same in WhatsApp, Telegram, Discord and in a post caption. Every platform draws emoji its own way — below you can see how triangular ruler is drawn in the open Noto, OpenMoji and Twemoji sets.

How the smiley looks on different platforms

Only openly licensed emoji sets are shown. Artwork from Apple, Samsung and other closed platforms is not reproduced. Emoji fonts and image sets.
