Unicode Block - Kana Extended-B

Kana Extended-B is a compact collection of sixteen characters added to support historical and specialized Japanese writing, specifically the hentaigana alternate kana forms that were once used in pre-modern texts. These glyphs, which represent variants of the standard hiragana, are encoded to allow digital preservation and accurate transcription of classical literature, handwritten documents, and calligraphy, particularly those from the Edo period and earlier. The block complements the larger Kana Extended-A and other kana-related blocks by filling a gap for less common but historically significant syllabic characters, ensuring that scholars and typographers can faithfully render these older orthographic practices without resorting to private-use or font-specific hack solutions. Its inclusion in modern standards facilitates research, digital humanities projects, and access to Japan’s literary heritage in plain text.
