After migration, all featured images using accentued characters in their file names are displayed "blanked" in the Media Library. Thus, not displayed by respective posts.

I've used the "Better Search and Replace" plugin to check and all URL are corrects. Checking by FTP, all files are present in wp-content/uploads folder.

I've noticed in media library that when a featured image has something like "é, à, ê..." or apostroph in its filename, it displays as a blank broken image.

The website is in french and all 500+ posts are in french too.

Can you help reattach those files please?
