What 雺 means
It names foggy air.
The early Chinese glossary Erya describes 雺 as weather descending while the earth does not answer. Shuowen, an early character dictionary, gives 霚 as a form; a Tang-era text uses 雺 for damp weather.
The fog reading of 雺 is a variant of 霧; a separate reading links it to 霿. If it displays as a box, your font lacks the character.
Literary or specialist in Chinese; routine writing uses 霧 or 雾.
Outside historical or Taiwanese Hokkien use, it may look like a typo.
Questions people ask
1Why does 雺 show as a box on some devices?
Because that device's fonts have no glyph for it. The character is still correct and still copies correctly — the box is a missing glyph, not a broken character.
