U+D21F "툟" Hangul Syllable Tyolh Unicode Character

U+D21F "툟" Hangul Syllable Tyolh is a precomposed syllable in the modern Korean Hangul writing system, representing the phonetic sound "tyolh." It is formed from the initial consonant ㅌ (t) and the medial vowel ㅛ (yo), combined with the final consonant letter ㅀ (lh), which is a compound cluster. This specific syllable is codified within the Unicode standard as part of the Hangul Syllables block, which assigns a distinct character to each possible syllabic combination in the Korean script. While it is a valid and encoded character, it is rarely used in everyday Korean text, as the sound "tyolh" does not appear in common native Korean vocabulary, making it an example of a theoretical or reserve character included for completeness of the writing system.
