This corrupted files
issue sounds very strange. As this is the first time we encountered such a problem we would like to investigate it. As a possible reason we suspected omitting of the last chunk of uploaded file. Please check this one and if you find everything OK you can send us the code where you save uploaded files. If you want you can you can open a separate support
ticket (in forum
ticket you can not attach files) in order to attach the example files.
About the french specific letters inside the file name.
I have logged immediately your report and our team will research on it.
