What 󠆃 means
It works only as the second character in a registered pair.
The base is a Han ideograph, a Chinese-derived character used in Chinese, Japanese, and some Korean writing. The pair lets compatible software choose one registered subset of its drawn forms, or glyphs; the selector number alone has no fixed shape meaning. The same selector may have a different effect after a different base.

Usually not; an unsupported sequence leaves no visible mark.
If the exact base-and-selector pair is unassigned or unsupported, Unicode says software should display the base character as usual and ignore the selector. A hidden-character view may mark its presence.
