U+FF7C "ｼ" Halfwidth Katakana Letter Si Unicode Character
Unicode Version 17.0
ｼ
U+FF7C "ｼ" Halfwidth Katakana Letter Si is a typographic variant of the full width katakana character シ, representing the syllable "shi" in the Japanese writing system. It belongs to the Halfwidth and Fullwidth Forms block, where it was designed to occupy half the width of a standard fullwidth character for compatibility with older computer systems or text environments that used a fixed grid of equal width cells. Despite its reduced horizontal space, it retains the same phonetic value and visual form as its full width counterpart, and it is commonly used in contexts such as legacy terminal displays, digital clocks, or mixed width text where space constraints require narrower characters.
