Oh I'm not saying it's wrong, just too imprecise (actually, since in France "sushi" is often synonymous with nigiri, when I posted the character earlier in a chatroom, someone made the remark that they were "maki, not sushi").
Also, what about "🏤" which is "U+1F3E4 EUROPEAN POST OFFICE"?
I see it here as a box with some kind of horn, Deutsche Post's logo as far as I know. Is this supposed to be localized in the future so that I can see the French Post's bird instead?
What is not satisfying is that the emojis feel both too incomplete (great, there's an eggplant and a tomato, now where's the bell pepper?) and too imprecise (okay, I have this nice maki emoji to show what I'm eating... oh wait, am I sure my friend will actually see maki?).
And sometimes they're just plain weird, what about "😤 U+1F624 FACE WITH LOOK OF TRIUMPH"? In all fonts I can find it looks like someone who's mightily pissed, maybe fuming because he spent so much time looking for the perfect emoji, only for their friend to see something completely different. That doesn't look like triumph to me.
A stylized bugle is a fairly universal symbol for the postal services in Europe, at least historically. I can't find a complete overview, but it looks like France is one of the very few exceptions.
