U+FFBB "ᄏ" Halfwidth Hangul Letter Khieukh Unicode Character

Unicode Version 17.0

U+FFBB "ᄏ" Halfwidth Hangul Letter Khieukh is a typographic variant of the Korean Hangul letter that corresponds to the sound of the aspirated velar plosive, similar to the "k" in the English word "key." It belongs to the Halfwidth and Fullwidth Forms block, where it is specifically classified as a halfwidth character, meaning it occupies only half the width of a standard fullwidth character to facilitate compatibility with East Asian text layouts that mix narrow and wide glyphs. This particular letter, when in its fullwidth form, is written as ᄏ (U+110F), and in the context of historical computer encoding, the halfwidth version was commonly used in early CJK (Chinese, Japanese, Korean) character sets to save space in environments with fixed-width fonts.
