What 톚 means
Read 톚 as one syllable within its Korean word.
The block combines ㅌ, ㅖ, and ㅈ, three Hangul letters called jamo. If 톚 appears in Korean writing, read it as one syllable of the surrounding word. Fonts may change the parts' shapes or placement without changing the character's identity.
Hangul was devised in 1443; an explanatory manuscript for the system dates to 1446. Later Hangul texts included translations, practical books, and literature. Hanja means Chinese characters used in Korean writing; it is a separate tradition, not the source of Hangul.

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.
