What 鉴 means
It means “mirror,” “examine,” or “learn from a precedent.”
The older image is looking into a basin or bronze mirror. From that came “inspect” or “judge,” then a lesson or standard drawn from a person or past event.
Bronze inscriptions from the late Spring and Autumn period use 鑑 for a bronze vessel. The object gives a concrete starting point for the move from seeing a reflection to judging what one sees.
Why does 鉴 appear as 鑑 or 鑒?
They are traditional written forms with overlapping senses.
Simplified Chinese writes 鉴; traditional Chinese uses 鑑 or 鑒. The core senses overlap, but usage can differ: mirror-related compounds tend to use 鑑, while formal letter closings often use 鑒 to ask the recipient to inspect the text.
Read the whole word: the best English gloss changes with the compound.
What does 鉴 mean in Japanese?
Japanese 鑑 connects “mirror” with comparison and appraisal.
In Japanese, 鑑 is read かがみ for “mirror”; かんがみる means to consider something in light of a comparison. Compounds such as 鑑賞, 鑑定, and 鑑別 mean appreciating, appraising, and distinguishing, so the whole word sets the sense.
In Chinese, 鉴 sounds learned and deliberate when it means examining, judging, or drawing a lesson from precedent.
For an everyday mirror, 镜 or 鏡 is the ordinary character; 鉴 can sound abstract or formal.

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.
