U+B913 "뤓" Hangul Syllable Rweolh Unicode Character

U+B913 "뤓" Hangul Syllable Rweolh is a precomposed syllable used in the modern Korean writing system, Hangul. It represents the phonetic sequence "rweolh," where the initial consonant "r" is combined with the vowel "weo" and the final consonant cluster "lh," though in standard Korean pronunciation the initial "r" typically becomes an "l" sound in initial position. This specific syllable is extremely rare in contemporary Korean vocabulary and is often encountered only in specialized linguistic contexts, historical texts, or as part of foreign loanword transliteration, making it a seldom used but structurally valid component of the Unicode Hangul Syllables block.
