Incorrect Remapping of / Key with < on Italian Keyboard

[matijasss]

Issue Summary:

The / key on an Italian keyboard is incorrectly remapped to < when using Karabiner. This remapping occurs despite the correct virtual keyboard setting being set to ISO. If I quit Karabiner it works correctly.

Expected Behavior:

The / key should remain mapped as / and not be remapped to < when using Karabiner with an Italian keyboard.

Observed Behavior:

The / key is incorrectly remapped to <, creating unintended behavior and making it impossible to type / without additional workarounds.

Steps to Reproduce:

1.	Use an Apple M1 Pro device running macOS with an Italian keyboard.
2.	Ensure the virtual keyboard in Karabiner settings is set to ISO.
3.	Attempt to type / using the physical keyboard.

Additional Details:

•	The issue persists across applications, indicating it is a system-wide problem within Karabiner’s remapping logic.
•	Verified that the virtual keyboard setting in Karabiner preferences is correctly set to ISO, matching the physical keyboard layout.

Request:

Please investigate the incorrect remapping behavior for Italian keyboards on macOS and provide a fix.

System Information:

•	Device: Apple M1 Pro
•	Keyboard Layout: Italian
•	macOS Version: 15.0.1 (24A348)
•	Karabiner Version: 15.3.0

The same thing is happening for me on a British keyboard layout.

I have my virtual keyboard type set to ISO, and my keyboard layout in system settings set to "British - PC" (note this is not the default of "British".)

I expect the key under esc to be a "`" but instead it is a "" which is the "British" layout, not a "British - PC" layout.

This has happened since upgrading to the most recent karabiner elements that required me to set a virtual keyboard type of ISO

Same problem on German keyboard here: the key below Esc (^/°) is switched with the key to the right of Left Shift (</>). Uninstalling 15.3.0 and reinstalling previous Karabiner versions shows this issue was introduced with 15.1.0; 15.0.0 is the last version not affected. So for the time being the workaround is to simply stick to 15.0.0 until the bug is fixed.

As a workaround changing the Virtual Keyboard to ANSI will fix the issue...
