Cannot format text in a component's property

Hi community!

I am having a problem in a website with different languages. In Spanish and Catalan when using an english word we need to make it ITALIC. What is the problem?

I created a component with an image and some texts. And Made the texts editable properties. The problem is that I cannot format the text from the editable field from component.

Is there any way to accomplish this? I tried with embed HTML but I cannot make the embed content a property.
