Problem with encoding when uploading to hosting. How to be?

Question

PHP

Hello! I uploaded the site to the hosting, and found the following problem: the menu that is loaded from the database is displayed as question marks. I have read a bunch of articles on different forums. They simply loaded the dump in a different encoding, or the title was different. The header file is connected to all pages:
header('Content-type: text/html; charset=utf-8');
Dump: /*!40101 SET NAMES utf8 */;
Server encoding: UTF-8 Unicode (utf8)
Everything is as it should be, everything works on LAN in Windows and Linux, I did not change the encoding, this page is UTF-8, as well as on all the others. Help me please! Thanks in advance!

Answer 1

Are the files saved in utf8?
what is the encoding in mysql?
Try to change such a request in the database to make SET CHARSET utf8
and it is still possible to change through htaccess
AddDefaultCharset utf-8

Answer 2

I had this problem after installing the counters, when I moved the utf8 encoding back to the beginning, everything worked fine)
Well, maybe you have another reason ..
