You mean, you'd like to see which characters are "double-width"?  We
could add that, but on GUI frames that would just confuse, because
those "double-width" characters more often than not take less than two
full columns, especially if you happen to use variable-pitch font for
such exotic characters (something that happens quite a lot).

The width information is only more-or-less accurate on text-mode
terminals.  I wonder how to avoid confusing users with this.

Does anyone have ideas?
