What 멦 means
It spells one syllable, not a complete word.
Hangul groups letters into syllable blocks. In 멦, initial ᄆ, vowel ᅦ, and final two-consonant cluster ᆹ combine; a Korean word supplies the meaning.
Why was Hangul created?
To give Korean a simpler writing system.
Earlier Korean writing borrowed Chinese characters; systems such as Idu, Gugyeol, and Hyangchal adapted them to Korean. King Sejong devised Hangul in 1443; the 1446 book Hunminjeongeum explained its purpose and design. Hangul gained official status in Korea in 1894.

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.
