U+FFBA "ﾺ" Halfwidth Hangul Letter Chieuch Unicode Character

U+FFBA "ﾺ" Halfwidth Hangul Letter Chieuch is a typographic variant of the Hangul consonant Chieuch (ㅊ), designed to occupy half the width of a standard fullwidth character for compatibility with East Asian text environments that use a monospaced grid, such as older terminal displays or character cell layouts. It belongs to the Halfwidth and Fullwidth Forms block, which was created to facilitate interoperability between legacy CJK (Chinese, Japanese, Korean) encodings and modern Unicode. In practice, this halfwidth form is used to represent the sound "ch" in Korean romanization, but its usage has declined with the shift to proportional fonts and modern text rendering systems.
