U+1B042 "𛁂" Hentaigana Letter Sa-7 Unicode Character

U+1B042 "𛁂" Hentaigana Letter Sa-7 is a specific variant form of the Japanese kana character for the syllable "sa," belonging to the hentaigana set of historical and stylized alternative cursive scripts used in pre-modern Japan. This character is encoded in the Unicode standard's Supplementary Multilingual Plane, specifically within the Kana Extended-B block, which was added to support the comprehensive representation of these obsolete but culturally significant letterforms. Unlike the standard modern hiragana "さ," this hentaigana glyph showcases a distinct calligraphic stroke style, reflecting the diverse handwriting traditions that existed before the standardized Japanese writing system was established in the early 20th century. Its inclusion in Unicode ensures that scholars, typographers, and enthusiasts can accurately digitize, display, and preserve historical Japanese texts and artistic works that utilize these unique character shapes.
