Специальные символы различия XAMPP и NGINX

Я мигрирую систему, которая работает в xampp, на nginx,

поэтому специальные символы в xampp работают нормально, но в ошибке nginx,

любой намек на решение этой проблемы, xampp php и 7.2.5, и nginx php и 7.3.5

набор символов по умолчанию сервера - UTF-8

PHP также UTF-8

Кто-нибудь еще имел эту проблему?

ошибка, которую он дает в API:
