"Un œuf et des fruits."
How necessary is the ligature?
One time (very long ago as you can tell by the page layout) I ran into this question: http://i.imgur.com/Z8qMLn6.jpg
As you can see the only difference is whether or not l'e dans l'o is used. According to the Wikipedia sight: http://en.wikipedia.org/wiki/%C5%92 it is always necessary and says that it is actually wrong to write "soeur"... is that correct?
Should I try and use oe whenever possible? Is it outdated? Some sites don't even offer it for input (like Memrise), and other references for alt codes don't even mention it: http://www.alt-codes.net/french_alt_codes/
The whole thing is really confusing to me.
What I can tell you is that young pupils learning to write actually form the ligature which is, as far as I know, still compulsory. Now, if your software does not allow to do it, drop that, don't worry. Just for your information, using the French MO Word software, I can tell you that the correction is made automatically.
