I tried few variants. Like here:
How to send Emoji with Telegram Bot API?
python telegram telethon how to send emoji
And each variant of encoding from this page https://www.fileformat.info/info/unicode/char/1f4b5/index.htm
But nothing helped for me.
I tried to escape backslashes and to not. So I get this U0001F609
or this \U0001F609
in Telegram message.
Can somebody just show me JSON which I have to send in order to finally receive a smiley in the message?
