11 — History
Where the 📐 Triangular Ruler emoji came from
This one is older than Unicode emoji: Japanese carriers were drawing it on their handsets years before the standard existed, which it finally joined in 2010.
Same character every time — U+1F4D0 never changed. Only the drawing did, and only because each vendor redraws its own set. Someone on an older phone still sees the older picture.
Long before Unicode had emoji, Japanese carriers shipped their own picture sets.
📐 existed there as
KDDI au E4A2.
Those codes are why it survived into the standard at all — Unicode had to keep Japanese messages readable.
Triangular Ruler was approved as U+1F4D0 and shipped in Emoji 0.6 (2010). Emoji 0.6 is the original 2010 batch that came over from the Japanese sets.
Every vendor keeps its own artwork, so 📐 is redrawn by Apple, Google, Twitter / X, Facebook, OpenMoji, Samsung, Microsoft, WhatsApp, JoyPixels. The character you send never changes — only the picture does.
