This only occurs in Anki.
I also have the 'shift " = @' problem in all applications. I have set the regional setting to English UK but nothing seems to cure it.
I am using a K120 Logitech keyboard which I brought back from Thailand, plugged into a USB on my laptop.
I can live with the shift " bit but I'm getting sick of cutting and pasting ฉ.

Thanks in advance.
