U+FE4F "﹏" Wavy Low Line Unicode Character
Unicode Version 17.0
﹏
U+FE4F "﹏" Wavy Low Line is a typographic symbol categorized as a combining or spacing low line variant within the CJK Compatibility block, designed primarily for use in East Asian text to indicate a prolonged or wavy underline beneath characters, often employed in vertical writing or as a stylistic emphasis marker in Chinese, Japanese, or Korean typesetting, where it differs from a standard straight low line by its sinusoidal waveform, and while it appears in legacy compatibility encodings, it serves a distinct visual role in representing a gentle, wavy underscore rather than a regular punctuation or diacritical mark.
