Political Flags for languages

Great app, i love it thanks. ❤️ Just a comment, normally i'm not a fan of the idea of websites or apps identifying languages by a flag because it brings a lot of unnecessary political FUDs and noise and debates. As far as I know only designed languages like Esperanto or Lojban, etc have some sort of graphical symbol.

Btw, the catalan UTF flag does not show in my Firefox browser or Chromium, maybe bcs it's old or i need some extra plugin, i don't know... Normally the flag is this one: https://commons.wikimedia.org/wiki/File:Flag_of_Catalonia.svg

Anyway my suggestion would be to get rid of flags and just reinforce it with the ISO Code (ex. FR/EN/ES/CA) etc.
