U+FF5E "～" Fullwidth Tilde Unicode Character

U+FF5E "～" Fullwidth Tilde is a typographic variant of the standard tilde (~) specifically designed for use in East Asian text, where it occupies the same width as a CJK (Chinese, Japanese, and Korean) ideograph. Unlike its narrower ASCII counterpart, this fullwidth form is commonly employed in Japanese and Chinese writing to indicate ranges, such as dates or numbers, to represent a prolonged sound in manga and informal dialogue, or to signify a waving or wavy effect in decorative text. It is distinct from the similarly shaped wave dash (U+301C) used in Japanese punctuation, though both symbols share a visual resemblance and are often confused in digital typography.
