Rare Han character 䀛

It means squinting to see far or gazing for a while.

The Shuowen Jiezi, a Chinese character dictionary completed around 100 CE, describes closing or narrowing the eyes to see far, then gives a prolonged gaze as a related sense.

Why does 䀛 have a dawn reading?

Dawn is recorded, but its place in this text is disputed.

Other dictionaries also record looking askew, dimness, or darkness. A Taiwanese character-variant dictionary preserves the dawn reading in 䀛昕, citing an old poem by Ban Gu. Duan Yucai, a commentator, argued that 昒/曶—a character for dawn and dimness—belonged in the poem instead, and that a copying error introduced 䀛 into the text and then influenced the dictionary entry. Treat dawn as documented but contested, not as the settled original meaning.

Can I send 䀛 in a message?

Only if the reader expects a rare classical character.

A reader of classical texts may recognize a local sense; in casual chat, someone else may take it for an accidental paste or a font problem. Add a short gloss when the intended reading matters.

Without a quotation, use ordinary words for a modern reaction.
