Hi, @AzkabanPresident, this is dependent on the font that you use. If the font has these glyphs available, then it should show. Could you share with us a project that is not working as expected.

Yes.I change font now it works,thanks.I have another question,can I use system default fonts?Because custom font I use is too big

@AzkabanPresident we've not started work into enabling system fonts for Flutter. Work for this is underway for our native iOS and Android runtimes. But we've not started an investigation to explore what the effort would be to support a system fallback system for Flutter
