What’s the recommended approach for using (or avoiding) special characters in the App Store keyword metadata?

I am submitting an app to the App Store and want to understand the best way to handle keywords that include special characters.

If a keyword has accents like coração and users may search for coracao without accents, should I include both versions or rely on Apple to match them automatically?

What’s the recommended approach for using (or avoiding) special characters in the App Store keyword metadata?
