Flutter Text widget doesn't recognize some characters, shows "?" instead

Question

I'm trying to display text using the Text widget but it's not displaying properly. It shows the "?" for characters it cannot read. How can I fix this?

This is the result I want. And this is the error.

Answer 1

It is generally due to the special characters not being supported by the charset / font. Hence, rendering as questions marks. Try some other font that has all those characters / glyphs.
