U+1B031 "𛀱" Hentaigana Letter Ku-7 Unicode Character

U+1B031 "𛀱" Hentaigana Letter Ku-7 is a rare historical variant of the Japanese hiragana syllable "ku" (く), classified as a Hentaigana, which are the non-standard, stylized forms of kana that were once widely used before the regularization of the Japanese writing system in the early 20th century. This specific variant, known as "ku-7," originates from a cursive abbreviation of the Chinese character 久 (meaning long time), and its inclusion in Unicode allows for the accurate digital representation of premodern Japanese texts, where such varied letterforms were commonly employed for aesthetic and calligraphic purposes.
