Web client exception on filenames containing % character

[Celti]

Steps to reproduce

1. Create a file with a % in the filename in a Nextcloud-synced folder, e.g., 99%.txt.
2. Attempt to load that folder in the web interface.

Expected behaviour

Nextcloud should display the folder's contents in the web interface, as normal.

Actual behaviour

The folder sits with an endless loading icon. In the browser console in Chromium, an uncaught URIError in client.js can be observed. Using WebDAV directly (e.g., DAVfs or the sync client) works normally.

GitMate.io thinks possibly related issues are #11780 (character % in filename), #7762 (Special characters in filenames), #4853 (occ files:scan - an exception occures if folder or file name contains a '+' character.), #9462 (Exception during scan), and #6860 (appstoreFetcher Exception).

[Celti]

Ugh, this is a dupe of #11780 but Github's search is silly and I didn't find it. Closing, sorry for the noise.
