About the search api, I can only search by "English" word, 500 error if I search Chinese or Japanese

It's English title is (The Brave "Yoshihiko")
It's Japanese title is (勇者ヨシヒコシリーズ)(https://www.netflix.com/jp/title/80075404)

When I use the search API from RapidAPI, it will return 500 error if I search a non-english title(勇者ヨシヒコシリーズ). It returns correct response when I search (The Brave "Yoshihiko").

Could you support for non-english users? Or could you provide me some other solutions to let me search for Chinese or Japanese?
