What 뗀 means
뗀 is the hangul syllable dden. Unicode classifies it as a letter and files it in the Hangul Syllables block; this site shelves it under Chinese, Japanese & Korean.
Its appearance depends on the font and text styling.
How it is encoded
뗀 is a single code point, U+B5C0. In HTML that is 뗀, and in CSS \B5C0.
Questions people ask
1Why does 뗀 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.
