Hentaigana Letter Ha-9

Hentaigana Letter Ha-9 at U+1B0A6 is a historic Japanese kana character for the syllable ha, encoded in the Kana Supplement block. It represents one of the variant cursive kana forms known as hentaigana, which were widely used before modern Japanese spelling standardized hiragana shapes. In practice, this character appears most often in academic work on Japanese paleography, classical literature, manuscript studies, and historical typography. Editors and researchers use hentaigana characters when they need to reproduce the actual writing found in old books, letters, temple records, signs, or woodblock prints rather than silently converting everything to modern は. It can also be used in museum catalogs, digital archives, fonts for classical Japanese, and educational material that teaches how to read premodern texts. Because many hentaigana forms share the same modern reading, “Ha-9” is an identifying label for this particular encoded shape, not a separate syllable or pronunciation. Outside specialist Japanese historical contexts, it is uncommon. Readers may not recognize it as kana, and font coverage is still less universal than for ordinary hiragana and katakana.
