What 𘴁 means
𘴁 is the tangut ideograph-18d01. Unicode classifies it as a letter and files it in the Tangut Supplement block; this site shelves it under Chinese, Japanese & Korean.
Its appearance depends on the font and text styling.
How it is encoded
𘴁 is a single code point, U+18D01. In HTML that is 𘴁, and in CSS \18D01.
Questions people ask
1Why does 𘴁 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.
