To change the default database encoding (for example, to UTF-8), open the PHPMyAdmin interface.

We recommend choosing the collation according to your CMS requirements or the developer’s recommendations:
utf8_general_ci or utf8_unicode_ci — suitable for most CMSs.
utf8mb4_unicode_ci or utf8mb4_unicode_520_ci — recommended for new CMS installations on MySQL 5.6.
utf8mb4_0900_ai_ci — recommended for new CMS installations on MySQL 8.
