Unicode Errors result in always re-download

Open sn00py1310 opened this issue 1 year ago • 3 comments

There seems to be a bug with Unicode detecting the same filename on the disk and the server differently. So it re-downloads the whole file every time.

Redownload is on default OS: Windows 10 Version: PFERD 3.4.3

Sounds like the file name is not unicode normalized on ilias, but at some point after downloading the file it is unicode normalized to NFC/NFKC. What file system are you running this on?

After further research, I could pinpoint the root cause of the issue. It's a combination of PFERD, ILIAS and synchronization tools. A lot of the tools for synchronization normalize the file-/foldernames. In my case, it's syncthing. There isn't probably a good solution in PFERD for this type of issue.

A setting (disabled by default) to normalize paths before applying transforms could maybe fix this.
