What 󠄙 means
It selects a registered glyph variant for the character before it.
An ideographic variation sequence (IVS) pairs a written character with a selector such as VS42. This lets a registered collection specify a particular glyph form for a name, historical record, research text, or publication.
The general variation-selector mechanism was documented in Unicode 3.2. VS42 was added in Unicode 4.0, after design work in 2003 refined supplementary selectors for collection-based ideograph forms. Different regions, historical records, and publishers can need distinct legitimate glyph forms, so the Ideographic Variation Database (IVD) registers pairs by collection.
Why is U+E0119 invisible?
It has no separate visible glyph of its own.
A font draws the selected form only if it has matching variation data for that registered pair. With an unsupported or misplaced selector, the base character usually looks unchanged; a text inspector or show-hidden mode can expose the control.
Technical and invisible: it matters inside text that needs a specific written-character form.
VS42 is not a space; without a preceding base character, it has nothing to change.

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.

A visible symbol can contain several code points. JS .length counts UTF-16 units; UTF-8 counts bytes.
