What 聠 means
Its old dictionary gloss means “ears shut.”
The 1716 Kangxi Dictionary cites Yupian for this gloss. Compiled around 543, Yupian grouped characters by shared written component (a radical) and gave pronunciations and definitions.
Why does 聠 become 聠?
Normalization maps 聠 to 聠.
Unicode encoded this form so text converted from Taiwan’s CNS 11643-1992 standard and back can retain its source character.
The sequence 聠 followed by UFE00 preserves the glyph distinction through normalization. UFE00 is an invisible variation selector, a mark for a specific glyph form.
Use 聠 in ordinary text; keep 聠 when the CNS 11643 source distinction matters.
Normalization can replace 聠 with 聠.

1Why does 聠 show as a box on some devices?
Not every system ships a font for the CJK Compatibility Ideographs Supplement block. Where none is installed, the character shows as an empty box; adding a font such as Noto fixes it. The character itself is still correct and copies correctly.
