Wave dash

Wave dash (U+301C 〜 WAVE DASH) is a character represented in Japanese character encoding, usually used to represent a range. The wave dash is similar to, but not the same as, the tilde character (U+FF5E ～ FULLWIDTH TILDE), which is often used interchangeably with it.

The vertical wave dash () is not currently included in Unicode, but there is a similar symbol available called the wavy line (U+2307 ⌇ WAVY LINE). It is created by rotating right (clockwise) the wavy dash symbol (U+3030 〰 WAVY DASH) to form a vertical wave-like pattern.

Wave dash is also written in vertical text layout. Vertical wave dash is the vertical form by rotation and flip in Unicode and JIS C 6226.[1][2]
