What 沿 means
It preserves the CNS 11643 code corresponding to 沿. T6-2C5B is its source position in Taiwan's CNS 11643 character set. The separate Unicode form lets software convert a CNS text into Unicode and back without losing its original CNS code.
NFC, a standard way to normalize Unicode text, changes 沿 to 沿. The text keeps the character but loses the distinction between the original codes.

Questions people ask
1Why does 沿 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.
