U+1B03F "𛀿" Hentaigana Letter Sa-4 Unicode Character

U+1B03F "𛀿" Hentaigana Letter Sa-4 is a historical variant of the hiragana character "さ" (sa), used in premodern Japanese writing as part of the hentaigana system before standardizing modern kana. This specific glyph represents the fourth of several known hentaigana forms for the syllable "sa" and derives from a cursive simplification of the Chinese character (kanji) 左, which historically contributed to early Japanese phonetic scripts. Though seldom used today, it appears in classical texts, calligraphy, and digital typography for accurate representation of historical manuscripts.
