This seems to be due to the `East Asian Ambiguous Character Width'.
w3m looks to do well[1].  So does my Emacs except for "※" [2].
eww is mostly ok but with no ruled line[3].

I guess it is related to the personal font setting and also how
Emacs choose one.  But I abandoned improving it years ago.  If
anything, I'm not capable to do that.

These lines should be the same width, but...
１＋１＝２
１−１＝０
１×１＝１
１÷１＝１
