How to add Russian characters to MySql in Django on encoding error?

Question

MySQL

In models, the field is like charfield.
English characters are entered without problems.
And the Russian is given an error.

Exception Type:	OperationalError
Exception Value:	
(1366, "Incorrect string value: '\\xD0\\x94\\xD0\\xB8\\xD0\\xBC...' for column 'title' at row 1")

The most interesting thing is that the project did not start from scratch, a foreign database was used, models were formed automatically, there are a lot of tables in the database, they read Russian characters.
The error appeared after creating and migrating a new model to the project (the rest of the models still function perfectly)
I will insert the model code:

class TbRecNews(models.Model):
    url = models.CharField(max_length=150)
    user = models.IntegerField()
    title = models.CharField(max_length=100)

Whether it is possible to solve this question 1) in models of the project? How?
2) in mysql config? How and where to look for the config itself?
Entered the command
mysqld --verbose --help grep character-set
Issued:

mysqld: Can't change dir to '/var/lib/mysql/' (Errcode: 13 - Permission denied)

Nothing has changed. The error remains.
Thank you in advance!

Answer 1

Check the database connection encoding in the DATABASES settings, check the created tables and make sure that the encoding is the same everywhere and ideally utf-8
