What 뤿 means
Enter ㄹㅜㅣㄱㅅ on a Korean two-set keyboard.
A Korean IME (input software that assembles Hangul as you type) combines the jamo (letters used to build syllable blocks): ㅜ + ㅣ forms vowel ㅟ, and ㄱ + ㅅ forms final cluster ㄳ after initial consonant ㄹ. The resulting block is 뤿.
What does 뤿 mean by itself?
It is a syllable block, not a complete message.
A Hangul block arranges letters into a square, with each block representing one spoken syllable. Here, ㄹ is the initial consonant, ㅟ the vowel, and ㄳ the final consonant cluster. Alone, that structure does not identify a particular word or message.
King Sejong created Hangul to represent Korean speech more directly than Chinese-character writing and make reading easier. At its introduction the script was called Hunminjeongeum (“Right Sounds to Teach the People”); its development was completed in 1443, and an explanatory book was published in 1446. Korean writing later combined Hangul with Hanja, the Chinese characters used in Korean texts, while modern Korean is generally written in Hangul. The square blocks can resemble Chinese characters, but their component letters are alphabetic parts, not copies of Chinese glyphs.
A language-specific text syllable; alone, it is a character sample, not a conversational reaction.

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.
