Hi! Are you sure you have UTF-8 encoding end-to-end (so for Java, and for OS)?
https://stackoverflow.com/questions/39185613/java-nio-file-invalidpathexception-malformed-input-or-input-contains-unmappable My first guess is you have a charset active/set either for java or the OS which does not support umlauts.

What is a good way to make file upload possible, with these type of filenames? Do i really have to overwrite FileUpload.getClientFileName? Maybe we can setup something completely different?
