U+0465 "ѥ" Cyrillic Small Letter Iotified E Unicode Character

U+0465 "ѥ" Cyrillic Small Letter Iotified E is a historical Cyrillic letter used predominantly in Old Church Slavonic and early Slavic manuscripts to represent a vowel sound that combined an initial "y" or "i" glide with the "e" vowel, typically corresponding to the sound of "ye" or "ie" in modern Slavic languages. It is the lowercase form of U+0464, and its usage declined after the orthographic reforms of the 17th and 18th centuries, being largely replaced by other letters such as "Е" with a preceding "Й" in Russian and related alphabets. This character is part of the Cyrillic Extended-A block and is of interest to linguists and scholars studying the phonological evolution of early Slavic writing systems.
