What 뿾 means
뿾 is the hangul syllable bbweoj. 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
뿾 is a single code point, U+BFFE. In HTML that is 뿾, and in CSS \BFFE.
Questions people ask
1Why does 뿾 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.
