U+FFB4 "ﾴ" Halfwidth Hangul Letter Pieup-Sios Unicode Character

U+FFB4 "ﾴ" Halfwidth Hangul Letter Pieup-Sios is a typographic variant of the Hangul consonant cluster representing the combined sounds of pieup and sios, which corresponds to the character 프 in its fullwidth form. This halfwidth character is part of the Halfwidth and Fullwidth Forms block in Unicode, specifically designed for use in contexts where character width must be standardized, such as in legacy East Asian computer systems or fixed-width text environments. It appears as a narrow, compressed version of the fullwidth letter, occupying the same horizontal space as standard ASCII characters to maintain alignment in monospaced layouts. The character is not typically used in modern Korean writing but serves a historical and technical role in preserving compatibility with older CJK encoding standards and terminal interfaces.
