It would be interesting to do a study, I would suspect those forms are still seen as 'classy', 'elegant' and 'better' -- non-lining figures and the like. But maybe that's just my own preference/hope, and in fact they are just seen as 'weird'.

But hey, everyone likes an actual em or en dash to two or one hyphen, don't they? No? Say it ain't so! (Not that anyone, including me, bothers to enter them on the keyboard, see above).
