U+FF74 "エ" Halfwidth Katakana Letter E Unicode Character
Unicode Version 17.0
エ
U+FF74 "エ" Halfwidth Katakana Letter E is a typographic variant of the fullwidth katakana character エ, designed to occupy a single byte width for compatibility with older computer systems or grid based text layouts, particularly in CJK (Chinese, Japanese, and Korean) computing environments. It represents the phoneme "e" in the Japanese katakana syllabary and is often used in contexts where monospaced or halfwidth characters are required, such as in terminal displays, legacy software, or when mixing with ASCII text. As part of the Halfwidth and Fullwidth Forms Unicode block, this character maintains visual alignment with other halfwidth symbols while preserving the same linguistic function as its fullwidth counterpart.
