Special chars in for MultipartFile file name converted into ? in spring boot

Question

I am wondering why does spring boot convert MultiPartFile file's name special characters into ? (for eg. ééé.pdf gets converted to ???.pdf). Do I need to configure Spring to disabled this behaviour ? I have checked my jvm configuration for file.encoding and it's already set to UTF-8.

I perform the file upload this way :

@PostMapping("/upload")
public void uploadFile(@RequestParam MultipartFile file){
// todo : ...
}

You can try this

 String originalFileName = URLDecoder.decode(file.getOriginalFilename(), "UTF-8");

Hope useful for you
