Why is there an encoding problem?

Question

HTML

I have a simple php site. The encoding in the database is set to utf8-general-ci
The page is set to:
<meta charset="UTF-8">
All static Russian text is displayed normally. Everything that came from the database has the form "???????". How to fix it?

Answer 1

Solved a problem. Added charset=utf8 encoding to PDO;

Answer 2

header('Content-type: text/html; charset=utf-8');
