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?
So, I see that in telegrams you need to send emoji as a UTF-8 entity (i.e. 🗂 / 💵, etc.).
But my problem was that the text that the bot sends is regulated from the site's admin panel and stored in the database. And in the table, I cannot change the encoding for the correct storage of such characters (I get ???? at the output).
The solution I came up with:
Right now I'm storing an HTML entity in the database (i.e. 🔝 / 💵 etc.) and before sending the message, I cut them out of the regular expression /&#.*;/mU and convert to correct encoding with mb_convert_encoding($match, 'UTF-8', 'HTML-ENTITIES')
I did not describe all these points in the original message because I myself did not fully understand why the telegram does not process what I am trying to send to it.
