U+115F "ᅟ" Hangul Choseong Filler Unicode Character

U+115F "ᅟ" Hangul Choseong Filler is a special invisible character used in the Korean writing system to represent a missing or empty initial consonant in a Hangul syllable block. It ensures proper syllabic formatting and spacing when a vowel, which typically requires a preceding consonant placeholder in modern Hangul, appears alone as the first character in a syllable. This filler is particularly important for legacy text processing and typographic correctness, as it maintains the structural integrity of syllable blocks without introducing a visible glyph.
