U+FFAB "ﾫ" Halfwidth Hangul Letter Rieul-Mieum Unicode Character

U+FFAB "ﾫ" Halfwidth Hangul Letter Rieul-Mieum is a typographic variant found in the Halfwidth and Fullwidth Forms block, representing a Korean Hangul syllable-final consonant cluster that combines the sounds of Rieul (ㄹ) and Mieum (ㅁ). It is designed to occupy half the width of a typical East Asian character, making it useful for compatibility with older text systems or environments where fixed-width character spacing is required, such as in certain legacy computing applications or terminal displays. This character specifically encodes the letterform as a single, narrowed glyph, preserving the phonetic value of the digraph while conforming to halfwidth typographic conventions.
