About this character

U+212A (K) is KELVIN SIGN, an uppercase letter in the Letterlike Symbols block. It belongs to the Latin script. It was added in Unicode 1.1 (1993).

Its lowercase form is U+006B k.

It is a canonical singleton: Unicode treats it as identical to U+004B K, and every normalization form (NFC, NFD, NFKC, NFKD) replaces it with that character. Text that must round-trip exactly should avoid it. See the normalization guide.
