Why doesn't MySQL database encoding change?

Question

MySQL

The customer had a problem that the Russian letters entered into the MySQL table were displayed as incomprehensible characters. I changed the table encoding to utf8mb4-unicode-ci, the problem was not solved. Then decided to change the encoding of the entire database in the phpMyAdmin home page, but the encoding just doesn't change! Why doesn't the encoding of the entire database change? And how else can you solve the problem with the display of Russian characters?

Answer 1

In addition to base encoding, there is also table encoding and individual column encoding.

Answer 2

Look at the connection encoding.
