Epiphany uses real ellipsis like this, and curly double quotation
marks (in opposition to the common, "vertical" one). Unicode gives us
a lot of unambiguous characters for situations like that, and many
people (ex. web standards people) think you should use them as often
as possible. I kind of agree with that, too, but as you said they are
hard to enter and most people don't like them that much. Recently I
talked to the rest of the pt_BR l10n team and we decided not to use
this "nice and hard" unicode chars.
