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?

Apple automatically normalizes accents and most special characters in App Store search, so you generally only need to include the accented version and avoid wasting keyword space on duplicates.
