CJK Symbols and Punctuation


Correct JIS wave dash.
Incorrect Unicode wave dash (1990–2014).


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

Usage notesEdit

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 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]
