About this character

U+1FFD (´) is GREEK OXIA, a modifier symbol in the Greek Extended block. It belongs to the Greek script. It was added in Unicode 1.1 (1993).

It is a canonical singleton: Unicode treats it as identical to U+00B4 ´, 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.
