U+1B0FB "𛃻" Hentaigana Letter Ru-4 Unicode Character

U+1B0FB "𛃻" Hentaigana Letter Ru-4 is a historical variant of the Japanese hiragana character for the syllable "ru", specifically representing the fourth known stylistic form of that kana as used in classical Japanese writing. Hentaigana are obsolete or nonstandard cursive forms of hiragana that were widely employed before the standardization of the Japanese writing system in the early 20th century, and this character belongs to the block of Unicode symbols designated for encoding such historical scripts. It is used primarily in scholarly contexts, such as the digital reproduction of ancient manuscripts, calligraphy studies, and linguistic research into Japanese phonetic history, rather than in contemporary everyday writing.
