We're not necessarily talking about Latin here. In Norwegian and Danish, � is not a ligature, but a separate sound almost unpronounceable by English speakers. Imagine the first A in "Adamant" or "Ass" spoken with a very broad Texan accent. It has very little logical connection with either a or e. This also goes for � (a+a) and �, of course. However, without understanding how this character is used in Scandinavian languages, this could easily be misunderstood.How do you know that? Either "Caesar" or "C�sar" is good Latin.
I totally agree. This goes for other ligatures as well. For instance, "@" is seldom broken into a+d, "&" is seldom broken into e+t, and "?" is very seldom broken into ~, although they COULD be, strictly speaking.However, breaking up the *character* � into separate glyphs for a and e goes against the reason why this character is at all encoded, and the *character* � must always be rendered ligated.
