`key` is an empty string in this case, causing `charCodeAt(0)` to return `NaN`, which when passed to `Clutter.unicode_to_keysym` now generates an error in gjs >= 1.67.3: ``` JS ERROR: Error: Argument wc: value is out of range for uint32 ``` And the symbolic keys like Backspace, Enter and Caps Lock would have their presses ignored. Just skip the call to `charCodeAt` that will fail and allow `Clutter.unicode_to_keysym` to return its usual error flag.
