U+FF6A "ェ" Halfwidth Katakana Letter Small E Unicode Character
Unicode Version 17.0
ェ
U+FF6A "ェ" Halfwidth Katakana Letter Small E is a typographic variant of the standard katakana character エ (e), rendered at half the usual width to fit within monospaced or fixed-width text environments, particularly in legacy Japanese computing systems. It represents the small, or "sokuon" equivalent for the vowel sound /e/, often used to indicate a shortened or muted pronunciation in loanwords or informal writing, though it is distinct from the more common small tsu (ッ). This character is part of the Halfwidth and Fullwidth Forms block in Unicode, serving a specific role in maintaining visual alignment in digital text where space is constrained, such as in terminals or older telecommunications formats.
