SUMMARY
When there are certain URL unsafe characters in a device name, the device fails to mount. It appears there is an incomplete "hack" in place for handling spaces in the device name, but it's not sufficient for handling `(` and `)`: https://invent.kde.org/network/kio-extras/-/blame/master/afc/kio_afc.cpp#L276


STEPS TO REPRODUCE
1. Rename an iOS device to have a `(` in the name (Settings -> General -> About -> Name). Let's say "iPad (2)" for example
2. Connect the device with USB cable
3. Click "Trust" on the pairing dialog if it shows up
4. `idevicepair validate` should succeed with "SUCCESS: Validated pairing with device xxxx-xxxx"
5. Now, try opening the device in Dolphin

OBSERVED RESULT
Error message "Loading canceled" in Dolphin
Error in console `kf.kio.workers.afc: Failed to normalize "iPad (2)" into a valid URL host, this is a bug!`

EXPECTED RESULT
Should work fine just like when there are no URL unsafe characters in the name.
