How can I include special charachters in a search?

For a search function on my website, i use the contains filter to return content from strapi. For example when i search the title of events: I’ll use the endpoint …/events?_locale=tr-TR&title_contains=Atışını

The problem is that some languages on my site have special characters (like the Turkish search string in the example). That causes the response to be empty, even though there is an event that has this string in the title.

Is there a workaround for this?
