U+1B046 "𛁆" Hentaigana Letter Si-3 Unicode Character

U+1B046 "𛁆" Hentaigana Letter Si-3 is a rare historical variant of the Japanese hiragana character "し" (si or shi), belonging to the Hentaigana block, which encompasses the many alternate, cursive forms of kana that were used before the modern standardization of Japanese writing during the Meiji era. Specifically, this character is classified as the third known variant for the syllable "si" and was traditionally employed in pre-twentieth-century texts, calligraphy, and manuscripts as a stylistic or regional alternative to the standard hiragana. Its encoding in Unicode ensures that scholars, linguists, and digital humanists can accurately represent and preserve these once-common but now obsolete letterforms in modern electronic documents and research.
