Code html in a product category

im working in a drinks web and one of the attributes is the location where the drink is originally, i want that not only shows the flag

I create a taxonomy call “Country” and tried the classic <img>name but only show me the text

I have a filter and there i use the propiety background to show the flag but for obvious reasons only show there and when i click in the product only show the text

I’ve been reading and searching and is a propiety of wordpress that prevents to insert html code in those thing

Is possible deactivate that function or i have to create a custom filter?
