Error using accented words in the search field.

Hello!

When I type a word with an accent in my search field, an error occurs. I got in touch with my hosting and they reported that there is a problem in my wordpress application.

See attached images

See the response from my server:
As I have verified that in your wordpress application its not recognizing foreign characters and query string that its converting the content in this format

There fore I suggest you to consult it with your developer to check the uni code character settings are supporting on codes

How to solve this?
Abs,
