U+1B009 "๐" Hentaigana Letter I-4 Unicode Character
Unicode Version 17.0
๐
U+1B009 "๐" Hentaigana Letter I-4 is a historical variant form of the hiragana character for the Japanese syllable "i", belonging to the set of hentaigana, which were alternative, stylized cursive scripts used in Japan before the standardization of the modern hiragana system in the early 20th century. This specific character is one of several obsolete ways to write the sound "i" and was derived from the cursive simplification of the Chinese character ไปฅ, reflecting the calligraphic diversity of pre-modern Japanese writing. It is encoded in the Unicode standard's Hentaigana block, which was added in version 14.0 to preserve and support the digital representation of these historical letterforms.
