Skip translating currency symbol

Hi,
I have a webshop page with Woocommerce where i have set kr (Norwegian) to be the currency. The problem is if someone is pressing English in Gtranslate menu, then “kr” is changed to “￡” (Pound).
I have tryed a lot of CSS and this code:
https://docs.woocommerce.com/document/change-a-currency-symbol/

But it always change back to “￡”. Any good ideas how to fix it?
