About this character

U+0451 (ё) is CYRILLIC SMALL LETTER IO, a lowercase letter in the Cyrillic block. It belongs to the Cyrillic script. It was added in Unicode 1.1 (1993).

Its uppercase form is U+0401 Ё.

It is precomposed. Under NFD it decomposes into U+0435 е + U+0308 ◌̈, and NFC recombines that sequence into this single codepoint, so both spellings are canonically equivalent and should compare equal after normalization. See the normalization guide.
