Multi-file upload on multi pages - Filenames with accents issue

I have a Multi-file upload on a multi-page form. When I upload a file with accent, the name after upload is displayed correctly. If a go to next or previous page and come back to the page with the multi-file upload, the accent in the file name are converted to a strange string.

Name of the file = été.pdf
Filename converted to: u00e9tu00e9.pdf

“é” are converted to “u00e9”.

Do you know how to avoid this ?
Is it a bug ?

Thank you
