U+FFB1 "ﾱ" Halfwidth Hangul Letter Mieum Unicode Character
Unicode Version 17.0
ﾱ
U+FFB1 "ﾱ" Halfwidth Hangul Letter Mieum is a typographic variant of the Korean Hangul consonant ᄆ, which represents the “m” sound and is known as Mieum. Unlike its fullwidth counterpart, this character is designed to occupy only half the usual character width, making it suitable for use in legacy computing environments or East Asian text layouts where characters are often arranged in a fixed-width grid. Its halfwidth form was introduced to facilitate compatibility with systems that historically used double-byte character sets, allowing Korean text to be displayed alongside other halfwidth characters without disrupting alignment or formatting.
