This logic is NOT true for shifted keystrokes. Actually, shifted keystrokes like ":", "?", "<" or ">" are still display characters and should be sent into the Input Manager

Hi Sorry, it's taken so long for someone to get back to you.

It looks like this exact fix was already in Emacs when the bug was
raised, so I'm not sure what's going on.

Are you able to confirm whether this now works as expected?
