Han Character 𣇫

12780/42720

𣇫 has two documented language-specific readings: Mandarin wǒ is glossed “bright” or “clear,” while Vietnamese Chữ Nôm uses it for thuở, a time in the past. The language around it is the clue.

Text symbol

What 𣇫 means

Chinese records link it to “bright”; Vietnamese Nôm uses it for “thuở.”

The Mandarin reading is wǒ. Chinese dictionaries connect 𣇫 with 皦, which can mean bright, white, or clear. Chữ Nôm is a historical Vietnamese writing system that uses Han-based characters; in it, 𣇫 is listed for thuở, meaning a time in the past, as in thuở xưa (the old days).

Where does the Chinese reading come from?

An old Chinese character dictionary preserves the “bright” gloss.

𣇫 appears in the Northern Song revision of Yupian, a Chinese character dictionary, under 日, the sun/day radical used for filing entries. The Kangxi Dictionary cites Yupian for the gloss “bright” and links 𣇫 with 皦.

Why does 𣇫 show as a box?

Your font may not have a glyph for this rare character.

The character can still be present in the text even when a font displays a blank or square. Choosing a font with Han character coverage may show it.

Why does 𣇫 show as a box on some devices?

Not every system ships a font for the CJK Unified Ideographs Extension B block. Where none is installed, the character shows as an empty box; adding a font such as Noto fixes it. The character itself is still correct and copies correctly.
