Checks

• I have read the FAQ section, searched the open issues, and still think this is a new bug.

Describe the bug you encountered:

I'm using a database located on my Synology using WebDAV. The path contains /Sécurité/ in it. The app won't save it properly when synchronized.
Workaround: use Securite instead.

Here is the traceback

Have you tried the pre release version v1.15-r1? My understanding is that this fixes the issue you have with WebDAV having non-ASCII characters.

I upgraded to 1.15-r1 and the problem persists for me (I have an Umlaut in my server address)

Nope, with Android I stick to release versions. I will make an exception for Keepass2Android and let you know if I have the same issue.

The upgrade to version 1.15-r1 seems to have fixed the issue. I used SécuritéTest/Testéàè.kdbx and it worked as expected i.e. modifications on the phone and on my linux ubuntu system using KeePassXC were seen from both sides. Thanks.
