U+1B01A "𛀚" Hentaigana Letter Ka-4 Unicode Character

U+1B01A "𛀚" Hentaigana Letter Ka-4 is a historic variant form of the modern Japanese hiragana character "か" (ka), part of the hentaigana set of alternative syllabary glyphs used in Japan before the standardization of kana in the early 20th century. This specific character originates from a cursive abbreviation of the kanji 加, and its inclusion in Unicode under the Hentaigana block helps preserve and digitally represent these classical Japanese writing forms, which are frequently encountered in historical documents, literature, and calligraphy.
