Special character in file name prevents transfer over SPICE webdav share

[craftzneko]

Describe the issue
Copying a folder over spice webdav share on a MacBook Pro m3 to a windows 11 ARM machine doesn't copy a file with a ? (filename?.txt). In this case no error is generated, which is preferable as without checking file counts you don't even know a file has been missed, wrongly assuming the copy was successful. It would be useful if the issue can't be resolved to warn of failures. To resolve the issue or workaround I can just remove the question mark to make it appear (to be clear it's not even visible on the share with a ? in)

Configuration

• UTM Version: 4.7.5 (115)
• macOS Version: Sequoia 15.5
• Mac Chip (Intel, M1, ...): M3 Pro

Crash log
No crash

Debug log
No crash, issue seems clear but let me know if you still need them as you can't reproduce.

Indeed Windows doesn't support "?" in the filename, among other characters (StackOverflow).

I guess this error can't easily be caught in UTM, as the file share happens via Spice WebDAV and so it would need to be caught there.
