I was expecting to see flag icon variations when searching for languages in a prominent search engine. As a result, it was prominently presented with chat icons using "A" and some symbol from Eastern languages. In our case, where we have geography mixed with linguistics - flags could mean different things . Although, it something that user cannot choose => we can put flags for languages as well.

With the country (going to be downloaded, present or absent on device), we have Earth as a symbol. However, its actually a country out of it, not full planet. Not that it makes icons easier...
