What 󠇥 means
Place it after the matching ideograph in a registered IVS.
An ideographic variation sequence (IVS) pairs a base character with a selector to request a specific, registered CJK glyph form. The base and the complete sequence determine the result; the selector number alone does not identify one universal shape.
This is digital text machinery for recording a chosen character form in plain text. The glyph distinctions it can preserve come from established Chinese, Japanese, and Korean writing traditions, including forms used in names, older texts, and regional practice.
Why is the selector invisible?
It has no visible glyph of its own.
A font and app that support the particular IVS can use the selector to choose the requested form. Without that support, they normally display the base character and ignore the invisible selector, so the requested form may not appear.
That fallback changes the display, not the sequence's intended reading. An unregistered pairing should not be used to exchange text.
Technical text machinery, meant for registered CJK sequences rather than decoration.
Alone, it produces no visible mark.

1Why does 󠇥 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.
