U+1B03C "𛀼" Hentaigana Letter Sa-1 Unicode Character

U+1B03C "𛀼" Hentaigana Letter Sa-1 is a historic variant form of the modern Japanese hiragana character "さ" (sa), part of the hentaigana set of alternative cursive kana that were widely used before the standardisation of the Japanese writing system in the early 20th century. This specific glyph was derived from the cursive style of the Chinese character "左" and represents one of several obsolete or alternate ways to write the syllable "sa" in classical and premodern Japanese texts. In modern contexts, this character is primarily of interest to scholars of historical Japanese calligraphy, paleography, and typography, as well as to enthusiasts of rare Unicode characters, as it is encoded in the Supplemental Multilingual Plane to preserve and enable digital representation of these traditional writing forms.
