What 󠇔 means
Only a supported pair selects a particular glyph variant.
An ideographic variation sequence (IVS) pairs an ideograph with a selector immediately after it. The registered pair identifies permitted glyph forms; one selector can mark different variants on different ideographs.
Why can it seem to do nothing?
Unsupported pairs leave the base form unchanged.
If a font or app lacks support for the pair, the ideograph keeps its default form; the selector has no visible glyph.
An early proposal called them “variant tags” in 1997. By 2001, cases included exact forms in personal names and East Asian glyph sets, plus Korean encoding work for the Tripitaka, a collection of Buddhist scriptures. The Ideographic Variation Database began registering agreed pairs in 2007.

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.
