Steps to reproduce

open folder containing # in iOS Nextcloud App

Reasoning or why should it be changed/implemented?

its a bug

iOS version

13.3.1

App version

2.25.9.2

Start by reproducing the issue in the iOS app with a folder whose name contains #, then inspect the WebDAV PROPFIND request and its URL encoding. Done means the folder opens successfully instead of returning a 405 error, matching the Android app behavior.
