Question marks instead of emoji when exporting from the mysql database to a .sql file

[Микола Расік]

I would like to export my emoji database, but I'm having a problem with the export. When I export my table to .sql some characters are replaced with "?". more precisely, the symbols of the flags. For example, such data (USA 🇺🇸 ☺) became such data after export (USA ?? ☺). I use mysql workbench. utf8mb4 is everywhere in the database. After exporting, I viewed the file through Notepad, there were signs "?" imported the same file into another database, the same "?" signs. Tell me, maybe someone knows how to be in such a situation)

I tried to put different encodings in the database, nothing works. looked through a bunch of different articles on this problem, could not solve anything, the problem remained
