MapKit JS not displaying results for chinese addresses

Hello


we are using MapKit JS and trying to get results with addresses in Chinese characters.


Example:

https://api.apple-mapkit.com/v1/geocode?q=%E6%B1%9F%E8%8B%8F%E7%9C%81%E5%B8%B8%E5%B7%9E%E5%B8%82%E6%AD%A6%E8%BF%9B%E5%8C%BA%E7%A7%91%E6%95%99%E5%9F%8E%E5%88%9B%E7%A0%94%E6%B8%AF&lang=en&mkjsVersion=5.25.0


And we always get the following result:


{


"results": []

}

Do we need to format the location differently ?

Thanks,
