Any feature that displays text in a tabular form, or otherwise needs
arbitrary text to align, yes.

I think ideally we should make each character as wide as char-width
says it should be, because a well-behaved text-mode application is
supposed to arrange text according to that.  It should be easy to do
that, but I'm afraid we will bump into characters whose char-width is
1, but which are much wider on display.  I don't know what to do in
that case.
