What 𮣿 means
𮣿 is the cjk unified ideograph-2e8ff. 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
𮣿 is a single code point, U+2E8FF. In HTML that is 𮣿, and in CSS \2E8FF.

1Why does 𮣿 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.
