Correct JIS wave dash.

Incorrect Unicode wave dash (1990-2014).

Particle

〜

1. The wave dash, used in some East Asian languages to indicate the starting point of a range.

Usage notes

When the Unicode Consortium included the wave dash of the JIS X 0208 specification, they made an error in the shape definition. The correct shape as defined in JIS X 0208 is up-down-up (from left to right) just like a tilde while the Unicode Consortium defined it as down-up-down. Unix operating systems show the correct shape as in JIS. Microsoft Windows showed the incorrect shape as in Unicode, and used the fullwidth tilde ～ for the wave dash because of the shape error. This disagreement may cause a data loss in Unicode texts between Unix and Windows. Unicode corrected the error in 2014.^[1][2]
