U+3164 "ㅤ" Hangul Filler Unicode Character

U+3164 "ㅤ" Hangul Filler is an invisible glyph used in the Korean writing system to maintain correct character spacing and syllabic block structure during text processing, particularly when a placeholder is needed for a syllable that has no initial consonant or final consonant. It is often exploited in digital environments as a zero width space to create blank text or bypass filters, because it occupies a space in the text without being visible to the reader.
