If a folder has a file/folder with non-UTF-8 in its name, its contents can't be listed in the webinterface

[eaon]

Steps to reproduce

1. Mount local external storage /Folder
2. Create a folder with some non-UTF-8 encoding $ mkdir ex$'\366'mple in /Folder
3. Try to browse /Folder with the owncloud webinterface

Expected behaviour

Show folder contents even with the bad encoding

Actual behaviour

In the browser, the view jumps back to the folder you tried to originally access it from. ajax/list.php response is empty but 200 OK. WebDAV is fine.

This is likely a duplicate of #20824.
The server needs to handle such errors more gracefully.

[eaon]

Hm I'm not sure it's exactly the same. I have umlauts that are listed fine, but with ex$'\366'mple the entire folder won't show its listing.

[PVince81]

It is the same.

Originally we thought it was an umlaut issue but in the end it turned
out to be the contents of the folder which had files with the \x08 character

[ma-schmid]

how could you get a file name with \x08 character created accidentially? Is this a encoding issue?
