U+B69B "뚛" Hangul Syllable Ddyoh Unicode Character

U+B69B "뚛" Hangul Syllable Ddyoh is a precomposed syllable in the modern Korean writing system, representing a single block character formed from the initial consonant "ㄸ" (a tense double t sound), the medial vowel "ㅛ" (the diphthong yo), and the final consonant "ㅎ" (the aspirated h sound). As part of the Hangul Syllables block in the Unicode standard, this character encodes the entirety of the syllable "뚛" as one codepoint rather than a sequence of individual jamo components, enabling efficient text processing and display for Korean language content. While it is a valid and properly constructed Hangul syllable, "뚛" is an extremely rare character in standard Korean vocabulary, appearing primarily in obscure historical contexts, transcribed loanwords, or specialized linguistic examples rather than in everyday contemporary usage.
