How do I handle non-latin characters (i.e. С крыш наших домов) in MySQL?

I’m using the mysql-connector-python library to connect and write to a MySQL 5.7 db. I’ve set the encoding to utf8mb4 with cursor.execute('SET CHARACTERS SET utf8mb4'), and even included it in my connect settings:

import mysql.connector
from mysql.connector import Error

sg_titles_db_settings = {
    'user': <user>,
    'password': <password>,
    'host': <host>,
    'port': <port>,
    'database': <db>,
    'charset': 'utf8'

def get_mysql_connection():
        db_connection = mysql.connector.connect(**sg_titles_db_settings)
        return db_connection
    except Error as e:
        print("Error: ", e)
        return False

But any non-latin (non-english letters), such as any eastern european alpha character or special symbols ( for example), is inserted as ?.

Here’s the error I receive if I don’t change the encoding:

1366 (HY000): Incorrect string value: 'xD0x9ExD1x82xD0xB2...' for column...

I don’t understand what I need to do in order to resolve this issue. Every article I stumble upon doesn’t seem to help.

Thanks in advance!
