What 𮠀 means
𮠀 is the cjk unified ideograph-2e800. Unicode classifies it as a letter and files it in the CJK Unified Ideographs Extension F block; this site shelves it under Chinese, Japanese & Korean.
Its appearance depends on the font and text styling.
How it is encoded
𮠀 is a single code point, U+2E800. In HTML that is 𮠀, and in CSS \2E800.
Questions people ask
1Why does 𮠀 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.
