Opencart Nginx Rewrite Space(%20) and Latin Characters Issue

I am running Opencart on Nginx. But I'm having trouble using some of the spaces or latin characters while searching the site. How can I use spaces and some latin characters (ooo...) with rewrite? So far, I haven't been able to solve the problem with my research on the internet. Please help me. I am grateful to you.

Here is my Vhost code; (Cloudpanel)

server {
  listen 80;
  listen [::]:80;
  listen 443 ssl http2;
  listen [::]:443 ssl http2;
  {{ssl_certificate_key}}
  {{ssl_certificate}}
  server_name example.com;
  return 301 https://www.example.com$request_uri;
}

server {
  listen 80;
  listen [::]:80;
  listen 443 ssl http2;
  listen [::]:443 ssl http2;
  {{ssl_certificate_key}}
  {{ssl_certificate}}
  server_name www.example.com;
  {{root}}
  {{nginx_access_log}}
  {{nginx_error_log}}
