U+B91F "뤟" Hangul Syllable Rweoh Unicode Character

U+B91F "뤟" Hangul Syllable Rweoh is a precomposed syllable in the modern Hangul writing system of the Korean language, formed by combining the initial consonant "ㄹ" (rieul) with the medial vowel "ㅝ" (wo) and the final consonant "ㅎ" (hieut). It represents a specific phonetic sound that, while valid in Korean orthography, is relatively rare and not commonly used in standard Korean vocabulary, making it an obscure element of the Unicode Hangul Syllables block that completes the systematic encoding of all possible syllable blocks based on Korean phonological rules.
