The Telegram messenger has begun replacing the sent emoji of the flag of Belarus with a white-red-white flag, which is massively used by protesters.
This flag was the state flag of the Belarusian People’s Republic in 1918-1919, as well as the state flag of the Republic of Belarus in 1991-1995.
It is noteworthy that the replacement occurs only if you send emoji in a separate message. If you add a flag to the text of the message, then there will be no replacement.
