How to fix encoding problem in mysql on Fedora 21 workspace?

Question

Character encoding

When trying to change the encoding through phpmyadmin to utf8_* , it changes it to utf8 mb4 _* (For example, utf8_general_ci to utf8 mb4 _general_ci).

Answer 1

There is nothing wrong with utf8mb4, it will simply reserve not three, but four bytes for a character, which allows you to encode all 0x110000 Unicode characters.
And by mistake - check the encoding of the database itself, tables and fields.

Answer 2

Sadness and trouble. I solved the problem by changing the encoding of the string. Now, when creating a table, I will not leave the "Comparison" field empty. Rsa97, thanks for the help.
