礼 variant

Not as encoded text; in Japanese, it is a variant of 礼.

Here, “variant” means an alternate way to write the same character, not a new meaning. 礼 refers to manners and etiquette, ceremonies, respect, and thanks. Its older form 禮 is explained through a vessel used in worship and the act of presenting offerings; the sense later extended to rules of conduct and courtesy.

Why can 𮕤 show up as a box?

Your font or app may not support this supplementary character.

𮕤 lies beyond Unicode’s basic multilingual plane, so the app must handle supplementary characters and the font must include this glyph. Without both, you may see a blank box or replacement symbol even though the text still contains 𮕤.
