What 월 means
Month in dates; Monday in weekday shorthand.
월 is the Hangul spelling of a Korean reading of 月, a Chinese character used for “moon” and “month.” This borrowed reading is called Sino-Korean.
The Dongguk Jeongun, a Korean pronunciation dictionary dated 1448, records an older Hangul spelling for 月; that entry does not establish that the old spelling was modern 월.

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.
