As of now, I’m just renaming my picture links manually as a workaround. Thanks for the help anyway!
I am not sure how it was originally done when the site was created, but as of now I am having trouble uploading through the Media Library (probably due to some weird file permission issues), so I have resorted to uploading through FTP and syncing with Media Sync as a temporary solution.
Thanks for the quick reply! After looking more into it, I’m not entirely sure if it is Media Sync’s fault or just some other part of my WordPress installation. The links in my media library point to the wrong filenames (thus only grey boxes show up there), while the link directly from media sync (“Already in …”) actually shows me the correct filename and links to the file.
I have found some more examples:
Å (U+00C5) being converted to Å (U+0041 and U+030A)
ö (U+00F6) being converted to ö (U+006F and U+0308)
