What 🆟 means
It marks a program as 8K.
In 2015, Japan’s Association of Radio Industries and Businesses (ARIB) proposed it for Unicode as a compact tag in electronic program guides—on-screen TV listings—so program details could travel as text across TVs, computers, and phones.
Don't confuse it with
18K
Plain 8K is two characters; 🆟 is one character with the box built in. Use plain text when ordinary search words matter.
Questions people ask
1Why does 🆟 show as a box on some devices?
Because that device's fonts have no glyph for it. The character is still correct and still copies correctly — the box is a missing glyph, not a broken character.
