What 궇 means
It contributes a syllable; the word supplies its meaning.
궇 combines three Hangul letters: ㄱ (starting consonant), ㅜ (vowel), and ㅎ (ending consonant). A blank box means the font lacks 궇.
Hangul was devised in 1443 to make Korean writing easier to learn; the explanatory book Hunminjeongeum appeared in 1446. Hangul was used alongside Hanja, Chinese characters used in Korean writing. In 1894, the Joseon government made Hangul its official script. Some scholars propose influence from the Mongolian Phags-pa script; that link 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.
