The wave dash (\u301C) has no vertical equivalent in Unicode (see https://en.wikipedia.org/wiki/Wave_dash). @Redv123, would you be able to create a small test case in HTML with some Japanese text in vertical mode and with this wave dash in order to see how it behaves in Firefox or Chrome ? About the horizontal bar (\u2015), we could map it on the vertical bar (\u007C).

In vertical mode, both Firefox and Chrome correctly display the vertical dash without differences.

I discovered other issues while testing on a Mac. In Chrome and Adobe Acrobat, the exclamation mark in vertical Japanese text is centered, rather than positioned at the right. The first picture shows the exclamation mark on the right which is probably a Linux problem.
