There are a lot of flags here, but I don't use them. Because I don't have a flag in the flag case. I do not have the flag of my homeland. If you could add one flag to the list of flags, it would be a wavy, energetic conversation, work, information platform for us before the telegram. Thank you!
Telegram can't just add a new emoji randomly - it wouldn't work outside of the app
I think it's too late. Because adding flag or any smiles into the os is not telegram or Durov's work. Many years ago (I don't know exact year) Smiles are created for Android and iOS and now it's nearly impossible adding another one. However you can use emojies of it (if it's exist). )
