If I upload a file named "zoë.jpg" with the DMS, the Title will be set correctly in the DMS tree. If I zip the file first (on OSX in Finder, right-click - create archive), then upload the zip file (in DMS, right click, choose Upload zip file), the Title will not be correct but6 contain a square. (See attached files)

The problem is that linking to this broken Title file will not work correctly, for instance in the new site designer Image Gallery paragraph, the images with a broken title will not be shown.
