What 듵 means
It represents one Korean syllable.
Jamo are Hangul letters; ㅌ is the final consonant, or batchim. Fonts can change the parts’ shape or position without changing the syllable.
King Sejong introduced 훈민정음 (“proper sounds to teach the people”) in 1443 as a way to write Korean. Its 1446 guide explained the letters and Chinese ideas about speech sounds. Earlier names included 정음, 언문, and 반절; 한글 (Hangul) appears in the early 1910s. As of 2026, Phags-pa influence remains debated.

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.
