U+FFDB "ￛ" Halfwidth Hangul Letter Yi Unicode Character

U+FFDB "ￛ" Halfwidth Hangul Letter Yi is a typographic variant of the fullwidth Hangul letter Yi (ᅵ), designed to occupy a narrower character cell, typically half the width of its fullwidth counterpart. It is part of the Halfwidth and Fullwidth Forms block in Unicode, used primarily in contexts like East Asian text processing, terminal emulation, or legacy character sets where space efficiency is important. This character represents the single vowel Yi, which corresponds to the vowel digit ㅣ in modern Hangul, and is used in conjunction with other halfwidth Hangul characters to form syllable blocks in a compressed layout, though it is less common in contemporary digital text than its fullwidth version.
